• How can I embed a youtube video using variable widths/heights for a dynamic width web page?

  - by Dan Gayle

  I want to set a youtube video to 100% width so that it scales appropriately in a dynamic width column on a web page I am designing. The problem is that the height doesn't behave like the height of an image. Instead of scaling proportionately, it either collapses (if set to "auto" or left blank) or it scales seemingly random if set to a percentage. How can I get it to remain proportionate while still dynamic?

• Silverlight 4 - Download an html page from a different domain IN BROWSER?

  - by SilverDark

  I am trying to download a page using Silverlight 4 (http://google.com/) from a different domain than where the app is hosted. I'm simply curious if this is possible in the browser. I know I can do it out of the browser, as I tried it already, but trying it in the browser gives a security exception (understandable). I'd like to know if this can even be done, and if so, how? Thanks in advance.

• How do I apply a servlet filter when serving an HTML page directly?

  - by Philippe Beaudoin

  First off, I'm using Google AppEngine and Guice, but I suspect my problem is not related to these. When the user connect to my (GWT) webapp, the URL is a direct html page. For example, in development mode, it is: http://127.0.0.1:8888/Puzzlebazar.html?gwt.codesvr=127.0.0.1:9997. Now, I setup my web.xml in the following way: <?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5"> <display-name>PuzzleBazar</display-name> <!-- Default page to serve --> <welcome-file-list> <welcome-file>Puzzlebazar.html</welcome-file> </welcome-file-list> <filter> <filter-name>guiceFilter</filter-name> <filter-class>com.google.inject.servlet.GuiceFilter</filter-class> </filter> <filter-mapping> <filter-name>guiceFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- This Guice listener hijacks all further filters and servlets. Extra filters and servlets have to be configured in your ServletModule#configureServlets() by calling serve(String).with(Class<? extends HttpServlet>) and filter(String).through(Class<? extends Filter) --> <listener> <listener-class>com.puzzlebazar.server.guice.MyGuiceServletContextListener </listener-class> </listener> </web-app> Since I'm using Guice, I have to configure extra filters in my ServletModule, where I do this: filter("*.html").through( SecurityCookieFilter.class ); But my SecurityCookieFilter.doFilter is never called. I tried things like "*.html*" or <url-pattern>*</url-pattern> but to no avail. Any idea how I should do this?

• Will a browser download a font-face even if it is not used in the page?

  - by Logan Koester

  It would be easier for development if I can just embed every typeface I'm likely to use, but I definitely don't want the extra HTTP requests for fonts that don't end up anywhere in the page. Can anyone enlighten me?

• How do I make a suckerfish/superfish CSS dropdown that sticks to the right hand side of the page?

  - by joeforker

  I am developing a CSS dropdown menu based on the suckerfish CSS. I would like to put it on the right hand side of the page but the menus extend from the leftmost edge of each menu to the right, instead of from the rightmost edge of each menu to the left (as is necessary to keep the rightmost dropdown menu from opening outside the visible area.) How do I position my suckerfish dropdown menus to extend to the left, instead of the right?

• Any tricks to stop flickering in between page transitions?

  - by SLC

  Specifically, I am using a .hta to display pages. As the content is local, pages load instantly, but there is flicker as they redraw. Are there any tricks you can use to stop it flickering or reduce the effect? I heard somewhere that page transition effects can help, but does anyone have any ideas? Keep in mind that as its a .hta file, I have more flexibility, and can run vbscript etc. and do fancy things.

• Is there a tool out there that lets you print a colour chart / palette of colours used on a web page

  - by undefined

  I want to print a table of the colours used in a web page that my graphic designer has produced - I have .png files at present and use Fireworks to view them. It would be great if there was a tool that lets you print a table with the colour and hex value so I can easily reference when programming. Anyone come across such a thing? Sounds to me like there should be a firefox extension or similar?

• How do I force a jQuery click event to proceed any control click event on ASP.Net page

  - by Cen

  I've found posts about making a click event with jQuery for a button, however I need a little more then that. When any postback occurs on a page, I need to fire off a jQuery click event. Based on a condition, I want to continue processing (including running the server-side event code after the jQuery code), or, perform a redirect. I'm not quite sure how to go about this. Your help is appreciated!
