输入文本框的动态宽度(HTML) [英] Dynamic width for input text box (HTML)
问题描述
我怎样才能有一个继承它的容器宽度的文本框?
例如,我有一个div里面有一个文本框。
< ; div id ='content'style ='width:100%;'>
< input type ='text'name ='txtUsername'>
< / div>
我想要做的是当我调整浏览器的大小时,文本框必须遵循宽度
使用上面的代码,只要我将浏览器调整为更小的宽度,文本框就会溢出它的容器。
这样
input
将适合容器宽度的100%,但不会因为添加 input
而溢出。 s $ pad $: #content input
{
width:100%;
box-sizing:border-box;
-moz-box-sizing:border-box;
}

How can I have a textbox that inherits the width of it's container?
For example I have a div that has a textbox inside it.
<div id='content' style='width:100%;'>
<input type='text' name='txtUsername'>
</div>
What I wanted to do is when I resize my browser, the text box must follow the width of it's parent div.
With the code above, the textbox always overflow it's container whenever I resize the browser to a smaller width.
You should use box-sizing:border-box
together with width:100%
.
This way input
will fit 100% of container's width but will not overflow it because of added input
's padding:
#content input
{
width:100%;
box-sizing:border-box;
-moz-box-sizing:border-box;
}
