Question

Given that we don’t know the div’s width beforehand?

My idea: Calculate the div ‘s width with JS, find a way to convert it to cols and the apply the css to the textarea onthe fly. But perhaps there ‘s no need to reinvent the wheel?

Answer 1

<textarea style="width:100%">* will work in most cases.

If it doesn’t, please provide more information!

_{* Note: for some reason, it will need the cols and rows attributes to validate. But setting a width or a height will override them, so put any value you want.}
