[英]How to manage textarea right side overflow in css?
I have to create two <textarea>
s in two different <div>
s and both are have to come in single line. 我必须在两个不同的
<div>
创建两个<textarea>
,并且两者都必须在同一行中。 And both <textarea>
s have to occupy 100% width (50% by each) in all types of screen. 在所有类型的屏幕中,两个
<textarea>
都必须占据100%的宽度(每个宽度为50%)。
However, when I am trying the second <textarea>
, the right side is overflowing and even I am not able to manage right margin (in CSS) for <textarea>
. 但是,当我尝试第二个
<textarea>
,右侧溢出,甚至我也无法管理<textarea>
右边距(在CSS中)。 How can I avoid right overflow for <textarea>
? 如何避免
<textarea>
右溢出?
.container { background-color: lightblue; border: 5px solid black; min-height: 500px; } textarea { width: 100%; height: 100%; border: 3px none #cccccc; margin: 10px 10px 10px 10px; border: 1px solid black; } .left { float: left; width: 50%; } .right { float: left; width: 50%; }
<div class='left'> <textarea>left </textarea> </div> <div class='right'> <textarea>right</textarea> </div>
Note the change in margin to textarea
. 请注意
textarea
边距变化。 That should do it! 那应该做!
.container { background-color: lightblue; border: 5px solid black; min-height: 500px; } textarea { width: 100%; height: 100%; border: 3px none #cccccc; margin: 10px 0px 10px 0px; border: 1px solid black; } .left { float: left; width: 50%; } .right { float: left; width: 50%; }
<div class='left'> <textarea>left</textarea> </div> <div class='right'> <textarea>right</textarea> </div>
you have to remove margin
from your textarea
because margin
calculated form the outer width of the element , you can use padding
to .conatiner
instead. 您必须从
textarea
删除margin
,因为从元素的外部宽度计算出的margin
,可以改为使用.conatiner
padding
。
and add a box-sizing
attribute to remove the border width from the calculate width 并添加一个
box-sizing
属性以从计算宽度中删除边框宽度
html,body,.container{ height:100%; margin:0; } .container{ background-color: lightblue; border: 5px solid black; padding:10px; display: table; width: 100%; box-sizing: border-box; } textarea { width: 100%; height: 100%; border: 3px none #cccccc; border: 1px solid black; box-sizing: border-box; } .left{ display: table-cell; width:50%; height: 100%; } .right{ display: table-cell; width:50%; height: 100%; }
<html> <body> <div class="container"> <div class='left'> <textarea>left </textarea> </div> <div class='right'> <textarea>right</textarea> </div> </div> </body> </html>
Remove margin. 删除边距。 Because you are assigning 50% to each left and right textarea.
因为您要为每个左侧和右侧文本区域分配50%。 so your total width will be 100%+10px;
因此您的总宽度将为100%+ 10px; so it will overflow on x-axis
因此它将在x轴上溢出
textarea {
width: 100%;
height: 100%;
border: 3px none #cccccc;
border: 1px solid black;
}
Remove margin from your textarea because margin calculated form the outer width of the element, and give display: table; 从文本区域中删除页边距,因为所计算的页边距是元素的外部宽度,并给出display:table; to container.
到容器。
