  • CSS Div Width Problem - Lining divs... widths seem to be off in IE7

    - by jlrolin
    So far, I'm doing this programmatically using VB.net/ASP.net: 'Create Container Div Dim ContainerDiv As New HtmlGenericControl("div") ContainerDiv.Style("width") = "100%" ContainerDiv.Style("clear") = "both" ContainerDiv.Style("text-align") = "left" ContainerDiv.Style("margin") = "0" 'Create Expand/Collapse Image Dim img As New Image img.ImageUrl = Page.ResolveUrl("~/images/minus99.jpg") img.Attributes.Add("onclick", "change(this.parent);") 'Create Company Display Dim lbl As New Label lbl.Text = Parsetext(pc.NAME) lbl.Font.Bold = True lbl.Style("font-size") = "16px" Dim NameDiv As New HtmlGenericControl("div") 'NameDiv.Style("background-color") = "#F0D3D3" NameDiv.Style("width") = "375px" NameDiv.Style("float") = "left" NameDiv.Style("margin") = "0" NameDiv.Style("display") = "block" NameDiv.Controls.Add(img) NameDiv.Controls.Add(lbl) ContainerDiv.Controls.Add(NameDiv) Dim SetupDiv As New HtmlGenericControl("div") SetupDiv.Style("background-color") = "#F0D3D3" SetupDiv.Style("width") = "210px" SetupDiv.Style("float") = "left" SetupDiv.Style("margin") = "0" SetupDiv.Style("display") = "block" 'SetupDiv.Style("position") = "fixed" ContainerDiv.Controls.Add(SetupDiv) Dim UsedDiv As New HtmlGenericControl("div") UsedDiv.Style("background-color") = "#CFF5CE" UsedDiv.Style("width") = "140px" UsedDiv.Style("float") = "left" UsedDiv.Style("margin") = "0" UsedDiv.Style("display") = "block" 'UsedDiv.Style("position") = "fixed" ContainerDiv.Controls.Add(UsedDiv) Dim RemDiv As New HtmlGenericControl("div") RemDiv.Style("background-color") = "#BEE0F7" 'RemDiv.Style("position") = "absolute" RemDiv.Style("width") = "210px" RemDiv.Style("float") = "right" RemDiv.Style("padding") = "0" RemDiv.Style("margin") = "0" RemDiv.Style("display") = "block" 'RemDiv.Style("position") = "fixed" ContainerDiv.Controls.Add(RemDiv) This should give me four DIVS inside a container DIV. Here's what it's coming out as: The correct blocks above the non-inline blocks are from a table with the same exact widths as the ones I'm using on the Divs. There isn't any CSS adding pixels to them, I don't think. I need to line these up, and I can't figure out where my problem is here. Any help would be appreciated.

  • Python: query a class's parent-class after multiple derivations ("super()" does not work)

    - by henry
    Hi, I have built a class-system that uses multiple derivations of a baseclass (object-class1-class2-class3): class class1(object): def __init__(self): print "class1.__init__()" object.__init__(self) class class2(class1): def __init__(self): print "class2.__init__()" class1.__init__(self) class class3(class2): def __init__(self): print "class3.__init__()" class2.__init__(self) x = class3() It works as expected and prints: class3.__init__() class2.__init__() class1.__init__() Now I would like to replace the 3 lines object.__init__(self) ... class1.__init__(self) ... class2.__init__(self) with something like this: currentParentClass().__init__() ... currentParentClass().__init__() ... currentParentClass().__init__() So basically, i want to create a class-system where i don't have to type "classXYZ.doSomething()". As mentioned above, I want to get the "current class's parent-class". Replacing the three lines with: super(type(self), self).__init__() does NOT work (it always returns the parent-class of the current instance - class2) and will result in an endless loop printing: class3.__init__() class2.__init__() class2.__init__() class2.__init__() class2.__init__() ... So is there a function that can give me the current class's parent-class? Thank you for your help! Henry -------------------- Edit: @Lennart ok maybe i got you wrong but at the moment i think i didn't describe the problem clearly enough.So this example might explain it better: lets create another child-class class class4(class3): pass now what happens if we derive an instance from class4? y = class4() i think it clearly executes: super(class3, self).__init__() which we can translate to this: class2.__init__(y) this is definitly not the goal(that would be class3.__init__(y)) Now making lots of parent-class-function-calls - i do not want to re-implement all of my functions with different base-class-names in my super()-calls.

  • Is it really necessary to have a competely validated Mark Up and css for SEO purposes

If these errors have to removed can someone please suggest the way to do so also.

  • Tools to make CSS sprites?

    - by Simon_Weaver
    Are there any good tools to make css sprites? IDEALLY I'd want to give it a directory of images and an existing .css file that refers to those images and have it create a big image optimized with all the little images AND change my .css file to refer to those images. At the least I'd want it to take a directory of images and generate a big sprite and the .css necessary to use each as a background. Are there any good photoshop plugins or fully blown apps to do this?

  • Blueprint CSS & Boks: strange behavior with prepend and append in FF and Chrome

    - by Shyam
    Hi, I am working a bit with Blueprint CSS framework and I stumbled upon Boks. I am pretty unfamiliar with the BPCSS framework, but it seems that when using prepend and append, Firefox and Chrome (both) are not liking the input. I generated the code from Boks and for my newbe eye-sight, I can't directly see what went wrong in the export. Even though the span-sizes are correct, they are mutated :S Please help me! <div class="container showgrid"> <!-- first row --> <div class="span-3 prepend-2" id="bar-menuitems"> </div> <div class="span-6 prepend-4" id="banner-logo"> </div> <div class="span-3 prepend-4 append-2 last" id="bar-socialmedia"> </div> <!-- second row --> <div class="clear span-20 prepend-2 append-2 last" id="pane-graphics"> </div> <!-- third row --> <div class="clear span-5 prepend-2" id="banner-xx1"> </div> <div class="span-5" id="banner-xx2"> </div> <div class="span-5" id="banner-xx3"> </div> <div class="span-5 append-2 last" id="banner-xx4"> </div> <!-- last row --> <div class="clear span-6 prepend-9 append-9 last" id="bar-footer"> </div> </div>

  • CSS selectors : should I make my CSS easier to read or optimise the speed

    - by Laurent Bourgault-Roy
    As I was working on a small website, I decided to use the PageSpeed extension to check if their was some improvement I could do to make the site load faster. However I was quite surprise when it told me that my use of CSS selector was "inefficient". I was always told that you should keep the usage of the class attribute in the HTML to a minimum, but if I understand correctly what PageSpeed tell me, it's much more efficient for the browser to match directly against a class name. It make sense to me, but it also mean that I need to put more CSS classes in my HTML. It make my .css file harder to read. I usually tend to mark my CSS like this : #mainContent p.productDescription em.priceTag { ... } Which make it easy to read : I know this will affect the main content and that it affect something in a paragraph tag (so I wont start to put all sort of layout code in it) that describe a product and its something that need emphasis. However it seem I should rewrite it as .priceTag { ... } Which remove all context information about the style. And if I want to use differently formatted price tag (for example, one in a list on the sidebar and one in a paragraph), I need to use something like that .paragraphPriceTag { ... } .listPriceTag { ... } Which really annoy me since I seem to duplicate the semantic of the HTML in my classes. And that mean I can't put common style in an unqualified .priceTag { ... } and thus I need to replicate the style in both CSS rule, making it harder to make change. (Altough for that I could use multiple class selector, but IE6 dont support them) I believe making code harder to read for the sake of speed has never been really considered a very good practice . Except where it is critical, of course. This is why people use PHP/Ruby/C# etc. instead of C/assembly to code their site. It's easier to write and debug. So I was wondering if I should stick with few CSS classes and complex selector or if I should go the optimisation route and remove my fancy CSS selectors for the sake of speed? Does PageSpeed make over the top recommandation? On most modern computer, will it even make a difference?

  • Override bits of a CSS class while inline?

    - by larryq
    I have an html img that is being styled by a CSS class. I would like to override the width and height values used in that class under some circumstances. I'm building this img tag using something called a TagBuilder class, provided by Microsoft for the .Net system, which allows developers to assign attributes to an html element. In this case a CSS class has been assigned to the img tag, and I can assign width and height attributes individually, but they're not taking precedence over the values set in the CSS class. My tag looks like this currently: <img alt="my link" class="static" height="240" id="StaticImage" src="http://imageserver.com/myImage.jpg" width="240"> The static CSS class has width and height values of 300 each, and as you can see I'm trying to override them with 240. It's not working in this instance but can I do it without a second CSS class?

  • Advantages of Singleton Class over Static Class?

    Point 1)Singleton We can get the object of singleton and then pass to other methods.Static Class We can not pass static class to other methods as we pass objectsPoint 2) Singleton In future, it is easy to change the logic of of creating objects to some pooling mechanism. Static Class Very difficult to implement some pooling logic in case of static class. We would need to make that class as non-static and then make all the methods non-static methods, So entire your code needs to be changed.Point3:) Singleton Can Singletone class be inherited to subclass? Singleton class does not say any restriction of Inheritence. So we should be able to do this as long as subclass is also inheritence.There's nothing fundamentally wrong with subclassing a class that is intended to be a singleton. There are many reasons you might want to do it. and there are many ways to accomplish it. It depends on language you use.Static Class We can not inherit Static class to another Static class in C#. Think about it this way: you access static members via type name, like this: MyStaticType.MyStaticMember(); Were you to inherit from that class, you would have to access it via the new type name: MyNewType.MyStaticMember(); Thus, the new item bears no relationships to the original when used in code. There would be no way to take advantage of any inheritance relationship for things like polymorphism. span.fullpost {display:none;}

  • GWT layout panels vs. CSS layout

    - by David
    I read an article entitled "Tags First GWT", in which the writer suggests using GWT for event-handling, and CSS for layout. I just don't know whether the benefit of GWT's cross-browser compatibility goodness outweighs the flexibility offered by pure CSS layout. GWT GWT 2.0 has some snazzy layout panels, but to get them to resize properly you really need to build the entire panel containment tree from the root panel down. It's an all-or-nothing thing, it seems. CSS You can use CSS to layout an application too, and I'm inclined to do just that, if only to justify my purchase of several books touting the 'semantic markup' gospel. The downside might be cross-browser incompatibilities, the prevalence of which I have yet to determine. Which way to go? What is your opinion? Are cross-browser problems bad enough, and prevalent enough, to warrant ditching my CSS books, and building with GWT layout panels?

  • Css editor with certain features

    - by user255408
    I need a light css editor with certain functions. Already downloaded and tried a few apps but still no luck, none of them fit my requirements. Actually, there is one, CssEdit (or TextMate), but unfortunately i'm a windows user... Already tried: built-in NetBeans IDE css editor (btw nice editor, the one i'm using now for css) IntelJ IDE (very good html and css editor, but using the entire ide just for this - that's crazy) ArduoCss (very buggy in win7 environment) Notepad Notepad++ (it rules, but as i said, i need something more functional for css editing) Style Master ( if i don't find anything else, probably i'll choose this one) Stylizer ( also might be my choice, but it's black interface kills me, also extremy noob-oriented, i even couldn't find a way to see the source code) Some of the features i am looking for: grouping by comments like here snippets autocomplete, if i type for instance f-s, it should recognize and expand it to "font-size" property color picker The editor must have at least the first feature that i listed above. Sorry for my poor english.

  • CSS formatter NOT based on CSS Tidy?

    - by Abdu
    I can't find a css formatter (web based or Windows app) which formats the css where it puts the open brace on its own line aligned with its close brace, plus indents the attributes. The web based css formatters out here seem to be based on CSSTidy which doesn't do what I want. I don't like this CSSTidy format: .example { font-size: 3em; } I want: .example { font-size: 3em; }

  • CSS selector for grouped iterations

    - by snaken
    Hi, I have a number of elements that i want to loop through as groups. Consider this HTML: <input class="matching match-1" /> <input class="matching match-1" /> <input class="matching match-2" /> <input class="matching match-2" /> <input class="matching match-2" /> <input class="matching match-3" /> <input class="matching match-3" /> // etc I want a CSS selector that would allow me to loop through these as groups so there would be - using this example - 3 iterations of the loop (one for match-1, one for match-2 and one for match-3). The 1,2,3 etc is a variable used for grouping but this is not fixed so it cannot rely on hard coding of these values. Is this even possible? I'll be using jQuery or prototype not that that should matter really. Thanks

  • JQuery: loop through elements with more than one css class name that share only the first class name

    - by omaether
    Hello, I'm trying to use JQuery to loop through several div's with more than one class name, that all have the same first css class name and each one has a different second class name, e.g. <div class="maintext blue"> </div> <div class="maintext purple"> </div> <div class="maintext chartreuse"> </div> <div class="maintext puce"> </div> <div class="maintext lime"> </div> In JQuery I have tried $(".mainText").each(function (i) $(".mainText.*").each(function (i) $(".mainText" *).each(function (i) $(".mainText .*").each(function (i) But it will not select any of the divs with class="mainText ..." thanks for considering the question.

  • CSS practices: negative positioning

    - by Corey
    I'm somewhat of a novice to CSS. Anyway, I noticed that an extremely common method used in CSS is to have negative or off-screen positioning, whether it be to hide text or preload images or what have you. Even on SE sites, like StackOverflow and this website, have #hlogo a { text-indent: -999999em } set in their CSS. So I guess I have a few questions. is this valid CSS? or is it just a "hack"? are there downsides to doing things this way? why is this so common? aren't there better ways to hide content?

  • CSS and HTML incoherences when declaring multiple classes

    - by Cesco
    I'm learning CSS "seriously" for the first time, but I found the way you deal with multiple CSS classes in CSS and HTML quite incoherent. For example I learned that if I want to declare multiple CSS classes with a common style applied to them, I have to write: .style1, .style2, .style3 { color: red; } Then, if I have to declare an HTML tag that has multiple classes applied to it, I have to write: <div class="style1 style2 style3"></div> And I'm asking why? From my personal point of view it would be more coherent if both could be declared by using a comma to separate each class, or if both could be declared using a space; after all IMHO we're still talking about multiple classes, in both CSS and HTML. I think that it would make more sense if I could write this to declare a div with multiple classes applied: <div class="style1, style2, style3"></div> Am I'm missing something important? Could you explain me if there's a valid reason behind these two different syntaxes?

  • Recommended requirements when outsourcing xhtml/css site building?

    - by András Szepesházi
    I'm considering outsourcing a part of our web application development project for freelancers, namely the site building part. What I mean by site building is the process of creating the xhtml/css template files, with dummy content, from a psd file (or any other graphical layout file). The resulting xhtml/css files will be used by our developers as templates for cms based page rendering. The cms in this case is Drupal, but that might not be of much relevance. I'm looking for a good set of requirements, that will result in good quality xhtml/css code, complying with today's standards leaves little to the freelancer developer's imagination in terms of what I need I'm thinking about requirements like: Valid XHTML 1.0 Transitional document type, validated by validator.w3.org Identical rendering in all modern browsers (FF, Chrome, Safari, Opera, IE7-8) and also in IE6 All opening and closing block-level elements should be properly commented, referencing the functional part of the user interface they belong to (menu, toolbar, content, etc) No inline CSS definitions And so on. How would you organize a list like that? What requirements would you add?

  • Can resizing images with css be good?

    - by Echo
    After reading Is CSS resizing of images still a bad idea?, I thought of a similar question. (too similar? should this be closed?) Lets say you need to use 10 different product image sizes throughout your website and you have 20k-30k different product images, should you use 10 different files for each image size? or maybe 5 different files and use css to resize the other 5? Would there ever be combination that would be good? Or should you always make separate image files? If you use css to resize them, you will save on storage (in GBs) but you will have slight increase in bandwidth and slower loading images(but if images are cached, and you show both sizes of the image would you use less bandwidth and have faster loads?) (But of course you wouldn't want to use css to resize images for mobile sites.)

  • How to go about unused CSS issues

    - by Saif Bechan
    I am running some speedtests on a blog, and I always get complaints about unused CSS. But this is not CSS that I never use, it is just not used on that particular page. Now I work in a structured way, but there still has to be some CSS in the file that will not be used, because you need it on another page. I do not think that using different CSS files on different pages is the way to go, I think you are much better off just creating one big file that can be cached. Now is there an elegant way of dealing with this, or do you just stick with it.

  • Change CSS EMs to Percentage Automatically.

    - by Zachary Brown
    I cheated on a small site I was working on and used a site builder (Web Dwarf by Virtual Mechanics) to save time. I didn't realize it at the time, but this builder specifies the width, height and positions using CSS EMs. Is there an automated tool out there that will read through the CSS and convert each EM to a percentage so it will display correctly on wide screens as well? Any help would be great! Thanks. Here is the CSS: http://pastebin.de/14055
