I have attempted to use this CSS to set the width of my form elements:
input[type=\"text\"], textarea { width:250px; }
If you look at this Fire
Try removing padding and borders. Or try making them the same for both elements
input[type="text"],
textarea {
width:250px;
padding: 3px;
border: none;
}
Or:
input[type="text"],
textarea {
width:250px;
padding: 0;
border: 1px solid #ccc;
}
INPUT and TEXTAREA elements often have some padding applied by the browser (varies by browser) and this can make things appear effectively wider than the assigned width.
UPDATE: also box-sizing: border-box;
is a handy way to set widths that that padding and border will eat into rather than add onto. See: http://www.paulirish.com/2012/box-sizing-border-box-ftw/
