将滚动条添加到< textarea> [英] Add a scrollbar to a <textarea>

问题描述

我想为textarea添加一个滚动条，以便它总是出现，即使没有什么可以向下滚动到。如果没有什么可以向下滚动到，我宁愿如果它可以变灰，表明没有什么下面。

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.

我该怎么办？ / p>

How would I do this?

推荐答案

您需要的是 overflow-y：scroll;

演示

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