如何在悬停时显示隐形文字输入框？ [英] how do i make an invisible text input box visible on hover?

问题描述

这似乎不适合我！

HTML

 < div id =box1> 
< form action => 
< input type =stringname =htmlcode/> 
< / form> 
< / div> 
  

CSS

 ＃box1 {
 width：100px; 
 height：100px; 
 border-color：black 4px 
} 
 input {
 display：none; 
} 
 a：悬停输入{
 display：block; 
} 
  

文本输入不可见或可见，但不响应悬停

解决方案

您没有 a 标签可以悬停显示输入...

将其更改为＃box1：hover input {display：block;} 将您的鼠标移动到框中时显示。

border-color：black 4px 也是无效的。如果你想设置边框颜色，你只能给它一个颜色，而不是颜色和大小。

这是一个 demo 显示了这两项修正。

It doesn't seem to work for me!

HTML

 <div id="box1">
     <form action="">
         <input type="string" name="htmlcode" />
     </form>
 </div>

CSS

#box1 {
    width:100px;
    height:100px;
    border-color:black 4px
}
input {
    display:none;
}
a:hover input{
    display:block;
}

the text input is either invisible, or visible but does not respond to hover

解决方案

You don't have an a tag that you can hover to show the input...

Change it to #box1:hover input{display:block;} so it will show when you move your mouse into the box.

border-color:black 4px is also invalid. If you want to set the border color, you can only give it a color, not a color and size.

Here's a demo showing both of those things fixed.
