HTML-CSS: Tips of the Day

Should I size a textarea with CSS width / height or HTML cols / rows attributes?

I recommend to use both. Rows and cols are required and useful if the client does not support CSS. But as a designer I overwrite them to get exactly the size I wish.

The recommended way to do it is via an external stylesheet e.g.

HTML Code:

<textarea> </textarea>

CSS Code:

textarea {
  width: 300px;
  height: 150px;
}
