-webkit- textarea失去顶级&垂直滚动条上的底部填充 [英] -webkit- textarea losing top & bottom padding on vertical scrollbar

问题描述

我有一个宽度固定的textarea元素，高度和没有调整大小，当垂直滚动条出现时，元素的填充（顶部和底部）被忽略。

这是一个plnkr演示： http://plnkr.co/edit/jOeYXqkOZk3FCT24BRrk?p=preview

发生这种情况（仅在Chromium，Linux版本上测试过）。

以下是textarea元素的样式：

  textarea {
 background-color：＃1c1b1b; 
 border-bottom：3px solid＃343434; 
 border-radius：4px; 
颜色：#fff; 
 display：block; 
 height：165px; 
 margin-bottom：21px; 
 padding：10px; 
 resize：none; 
宽度：90％; 
} 
  

*一种解决方案是将textarea元素封装到div中填充，但然后滚动条不会重叠该填充，并会看起来有点奇怪。
$ b $编辑：好吧，也许它不会看起来像我想的那么奇怪，但我只是想知道是否有一个更优雅修正，在CSS也许。

解决方案

我试图想出一个解决方法，取决于你自己的提示。你说得对，但还没有实现。 :)我刚刚编写了你的​​想法。我所做的就是将其封装在一个包装中，并在伪元素之前和之后设置，以隐藏顶部和底部部分。我希望这可以解决您的问题。

它也可以在Chrome，Firefox以及IE中完美运行。

  .container {width：90％; position：relative;} textarea {background-color：＃1c1b1b;边界：0; border-radius：4px;颜色：#fff;显示：块;身高：165px; margin-bottom：21px;填充：10px;调整大小：无;宽度：100％; border-radius：4px;}。container：before，.container：after {content：'';显示：块; height：10px;背景：＃1c1b1b;位置：绝对; left：4px;容器：之前{top：0px;}。container：after {bottom：0px;}

I have a textarea element with fixed width & height and no resize and when the vertical scrollbar appears the padding (top & bottom) of the element is ignored.

Here is a plnkr demo: http://plnkr.co/edit/jOeYXqkOZk3FCT24BRrk?p=preview
This happens only with Chrome (tested on Chromium, Linux version).

Here is my styling for the textarea element:

textarea{
    background-color: #1c1b1b;
    border-bottom: 3px solid #343434;
    border-radius: 4px;
    color: #fff;
    display: block;
    height: 165px;
    margin-bottom: 21px;
    padding: 10px;
    resize: none;
    width: 90%;
}

*One solution would be to wrap the textarea element inside a div with that specific padding, but then the scrollbar will not overlap that padding and will look kinda strange.
Edit: ok, maybe it won't look as strange as I thought, but I just wonder if there is a more elegant fix, within css maybe.

解决方案

I've tried to think of a workaround, depending on your own hint. You've got it right, but didn't implement it yet. :) I just coded your idea. What I did was to enclose within a wrapper, and setting before and after pseudo elements to just hide the top and bottom parts. I hope that would solve your issue.

It would also run perfectly in Chrome, Firefox as well as in IE.

.container {
    width: 90%;
    position: relative;
}
textarea {
	background-color: #1c1b1b;
	border:0;
    border-radius: 4px;
    color: #fff;
    display: block;
    height: 165px;
    margin-bottom: 21px;
    padding: 10px;
    resize: none;
    width: 100%;
	border-radius: 4px;
}
.container:before, .container:after {
	content:'';
    display: block;
    height: 10px;
    background: #1c1b1b;
    position: absolute;
    left: 4px;
    right: 18px;
}
.container:before {
    top: 0px;
}
.container:after {
    bottom: 0px;
}

<div class="container">
