Enable vertical scrolling on textarea (5 answers)

Closed 6 years ago.

I would like to add a scrollbar to a textarea, so that it always appears, even when there is nothing to scroll down to. If there is nothing for it to scroll down to, I would prefer if it could be greyed out, indicating that there is nothing below.

How would I do this?

回答1:

What you need is overflow-y: scroll;

Demo

textarea {
    overflow-y: scroll;
    height: 100px;
    resize: none; /* Remove this if you want the user to resize the textarea */
}

回答2:

Try adding below CSS

textarea
{
    overflow-y:scroll;
}

回答3:

You will need to give your textarea a set height and then set overflow-y

textarea
{
resize: none;
overflow-y: scroll;
height:300px;
}

textarea {
    overflow-y: scroll; /* Vertical scrollbar */
    overflow: scroll; /* Horizontal and vertical scrollbar*/
}
