如果鼠标在图片上，如何在图片上获取文字？

Question

我希望当我的鼠标在图像上时，我的图片上的文字变得模糊，我已经模糊了，现在我想在图片变得模糊的时候在图像上显示文字。这就是我现在所拥有的，但现在我不知道要在上面获取文本。我对此有点陌生，所以现在可能太高级了，但也许你们可以帮助我。

css:

.blur img {
          transition: all 1s ease;
}

.blur img:hover {
  -webkit-filter: blur(5px);
}

html:

<div class="blur">
  <img src="picture.png" alt="picture">
  <h1>Welcome!</h1>
  <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. 
   Aliquam ac varius arcu, sed luctus neque. 
   Nam varius sem vel nisi condimentum congue. 
</div>

Answer 1

考虑这个DEMO

我用过这个css:

.blur img {
          transition: all 1s ease;
}

.blur img:hover {
  -webkit-filter: blur(5px);
}
.blur:hover .inner{
    opacity:1;
}
.blur{
    position:relative;
    width:100px;
}
.blur span{
    position:absolute;
    top: 100px;
    left: 50px;
    font-size:24px;
    opacity:0;
}

HTML:

<ul class="img-list">
<li>
<a href="http://nataliemac.com">
<img src="http://geekgirllife.com/images/filename.jpg" width="150" height="150" />
<span class="text-content"><span>Place Name</span></span>
</a>
</li>
...
</ul>

CSS:

ul.img-list {
list-style-type: none;
margin: 0;
padding: 0;
text-align: center;
}

ul.img-list li {
display: inline-block;
height: 150px;
margin: 0 1em 1em 0;
position: relative;
width: 150px;
} 

span.text-content span {
display: table-cell;
text-align: center;
vertical-align: middle;
} 
span.text-content {
background: rgba(0,0,0,0.5);
color: white;
cursor: pointer;
display: table;
height: 150px;
left: 0;
position: absolute;
top: 0;
width: 150px;
opacity: 0;
-webkit-transition: opacity 500ms;
-moz-transition: opacity 500ms;
-o-transition: opacity 500ms;
transition: opacity 500ms;
} 

ul.img-list li:hover span.text-content {
opacity: 1;
}
