In the following code, both the INPUT and TEXTAREA elements render wider than they should. How can I limit them to 100% of the usable area within the div?
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
<style>
.mywidth{ width:100%; }
</style>
</head>
<body>
<div style="border: 3px solid green; width: 100px;">
<input class="mywidth" ><br />
<textarea class="mywidth"></textarea><br />
<div style="background-color: yellow;" class="mywidth">test</div>
</div>
</body>
</html>
Note: If I remove the DOCTYPE, it renders as expected, with the INPUT, TEXTAREA and inner DIV all the same width and not going outside the containing DIV.
Update: Not withstanding the default borders on those elements, it still appears to render incorrectly in IE7.
