How to center a textarea using CSS?
提问by Chris
Forgive me for asking such a simple question, I'm new to both HTML and CSS. Is there an easy way to center a textarea? I figured I'd just try using
请原谅我问这么简单的问题,我对 HTML 和 CSS 都是新手。有没有一种简单的方法可以使文本区域居中?我想我只是尝试使用
textarea{
margin-left: auto;
margin-right: auto;
}
but it (obviously?) didn't work.
但它(显然?)没有用。

The margins won't affect the textarea because it is not a block level element, but you can make it display block if you like:
边距不会影响 textarea 因为它不是块级元素,但是如果您愿意,可以使其显示块:
textarea {
display: block;
margin-left: auto;
margin-right: auto;
}
By default, textareas are display: inline
, which is why you can put them side-by-side easily, and why the text-align: center
answers work too.
默认情况下, textareas 是display: inline
,这就是为什么您可以轻松地将它们并排放置,以及为什么text-align: center
答案也有效。
The textarea can also be centered by putting it inside a flexbox containerlike this:
textarea 也可以通过将它放在一个flexbox 容器中来居中,如下所示:
<style>
div.justified {
display: flex;
justify-content: center;
}
</style>
<div class="justified">
<textarea>Textarea</textarea>
</div>

you wrap your textarea with a div, give it width and then you align it with text-align:center;
你用一个 div 包裹你的 textarea,给它宽度,然后你将它与 text-align:center;
