Tutorial :CSS: how to set the width of form control so they all have the same width?


Consider the following example:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"          "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">  <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">      <head>          <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>          <style type="text/css">              div { width: 15em }              input, textarea, select { width: 100%;                  -moz-box-sizing: border-box; -webkit-box-sizing: border-box; box-sizing: border-box }          </style>      </head>      <body>          <form>              <div>                  <input value="Input">              </div>              <div>                  <textarea>Text area</textarea>              </div>              <div>                  <select>                      <option>One</option>                      <option>Two</option>                      <option>Three</option>                  </select>              </div>          </form>      </body>  </html>  

On browser that support the border-box box sizing, this is rendered as I want:

On IE 6/7, however, this is rendered as:

How can I get the same rendering in IE 6/7 that I get in other browsers, without resorting to setting sizes in pixels?


This is not possible with CSS. I did some research and I found out that the same question was asked before here. The solution is to use this boxsizing.htc file and add the following line to your HTML head:

<!--[if lt IE 8]><style>input, textarea { behavior: url("boxsizing.htc"); }</style><![endif]-->  


The solution is to use CSS and JavaScript to replace form controls that browser vendors have conspired to make a pain to style. A select is just a drop down menu with an onmouseup event. JS-driven text editors (rich and simple) which can replace a textarea abound online. There are even libs just for this purpose. (Example)


A quick fix could be to IE6/7 browser-hack it with something like select { *width:102.5%; _width:102.5%; } though this may not line up to the pixel if too wide.


Maybe this could help you: CSS3 support for Internet Explorer 6, 7, and 8. From the page:

IE-CSS3 is a script to provide Internet Explorer support for several of the popular new styles available in the upcoming CSS3 standard.
