  • CSS- removing horizontal space in list menu using display inline property

    - by Kayote
    Hi All, Im new to CSS and have a set target of learning & publishing my website in CSS by the end of the month. My question: Im trying to build a CSS horizontal menu with hover drop downs, however, when I use the 'display: inline' property with li (list) items, I get horizontal spaces between the li (list) items in the bar. How do I remove this space? Here is the html: <div id="tabas_menu"> <ul> <li id="tabBut0" class="tabBut">Overview</li> <li id="tabBut1" class="tabBut">Collar</li> <li id="tabBut2" class="tabBut">Sleeves</li> <li id="tabBut3" class="tabBut">Body</li> </ul> </div> And here is the CSS: #tabas_menu { position: absolute; background: rgb(123,345,567); top: 110px; left: 200px; } ul#tabas_menu { padding: 0; margin: 0; } .tabBut { display: inline; white-space: list-style: none; background: -webkit-gradient(linear, 0% 0%, 0% 100%, from(rgba(255,142,190,1)),to(rgba(188,22,93,1))); background: -moz-linear-gradient(top, rgba(255,142,190,1), rgba(188,22,93,1)); font-family: helvetica, calibri, sans-serif; font-size: 16px; font-weight: bold; line-height: 20px; text-shadow: 1px 1px 1px rgba(99,99,99,0.5); -moz-border-radius: 0.3em; -moz-box-shadow: 0px 0px 2px rgba(0,0,0,0.5); -webkit-border-radius: 0.3em; -webkit-box-shadow: 0px 0px 2px rgba(0,0,0,0.5); padding: 6px 18px; border: 1px solid rgba(0,0,0,0.4); margin: 0; } I can get the space removed using the 'float: left/right' property but its bugging me as to why I cannot achieve the same effect by just using the display property.

  • Change and Maintain CSS Style of Button State

    - by TDDG
    I have 5 list items that act like tabs for a page stored in a Masterpage in a asp.net application. When the user selects a list item, I would like to redirect the the page, and change the class for that list item (tab) to show the active tab the user is on. What is the best way to dynamically change the class of the list item based on the user interaction with them, and maintain the state?

  • Django save_m2m() and excluded field

    - by jul
    hi, in a ModelForm I replaced a field by excluding it and adding a new one with the same name, as shown below in AddRestaurantForm. When saving the form with the code shown below, I get an error in form.save_m2m() ("Truncated incorrect DOUBLE value"), which seems to be due to the function to attempt to save the tag field, while it is excluded. Is the save_m2m() function supposed to save excluded fields? Is there anything wrong in my code?

    Is there a metadata attribute I can use to prevent a field from being accessible on the client in a WCF RIA services? I sure I have seen this before, but I'm drawing a blank and Google isn't helping. It would look something like [MetadataType(typeof(User.UserMetadata))] public partial class User { internal sealed class UserMetadata { private UserMetadata() { } public int Id { get; set; } [HideFromClientProxy] public string PasswordSalt { get; set; } } }

  • iPhone: no way to draw on screen outside drawRect?

    - by Seva Alekseyev
    Is there a way to draw on the iPhone screen (on a UIView in a UIWindow) outside of that view's drawRect() method? If so, how do I obtain the graphics context? The graphics guide mentions class NSGraphicsContext, but the relevant chapter seems like a blind copy/paste from Mac OS X docs, and there's no such class in iPhone SDK.

  • a constructor as a delegate - is it possible in C#?

    - by akavel
    I have a class like below: class Foo { public Foo(int x) { ... } } and I need to pass to a certain method a delegate like this: delegate Foo FooGenerator(int x); Is it possible to pass the constructor directly as a FooGenerator value, without having to type: delegate(int x) { return new Foo(x); } ? EDIT: For my personal use, the question refers to .NET 2.0, but hints/responses for 3.0+ are welcome as well.

  • Does it make sense to have a model with only static methods?

    - by Jamie Dixon
    Hey everyone, I have an ASP.NET MVC 2 project that I'm working on and I'm wondering where I should place some of my code. I currently have a UsersModel which consists of a bunch of static methods that operate against my data context. These methods include such things as: UserExistsInDatabase, UserIsRegisteredForActivity, GetUserIdFromFacebookId etc etc. Should these methods be inside a UsersModel class or would they be more suited to a user helper class outside of the models context? Cheers for any pointers.

  • instantiate object with reflection using constructor arguments

    - by justin
    I'm trying to figure out how to instantiate a case class object with reflection. Is there any support for this? The closest I've come is looking at scala.reflect.Invocation, but this seems more for executing methods that are a part of an object. case class MyClass(id:Long, name:String) def instantiate[T](className:String)(args:Any*) : T = { //your code here } Is close to the API I'm looking for. Any help would be appreciated.
