Move link image 5px up on hover

问题

How would I go about acheiving an effect similar to that on this site's portfolio page Solid Giant, with CSS and HTML?

I had thought that just putting something like this would work:

a img{
    margin-top: 5px;
}

a img:hover{
    margin-top: 0px;
}

But it did not work, even if I put the :hover on the link instead of the img. I scoured his code and css but I could not for the life of me figure this out. Help please :)

position: relative would work:

a img:hover{ position: relative; 
             top: -5px;}

note that position: relative reserves the space in the document flow as if the element were not moved. But I think in this case, that is not an issue.

Also see translate():

http://www.w3schools.com/css/css3_2dtransforms.asp

img:hover {
    -moz-transform: translate(-2px, -2px);
    -ms-transform: translate(-2px, -2px);
    -o-transform: translate(-2px, -2px);
    -webkit-transform: translate(-2px, -2px);
    transform: translate(-2px, -2px)
}

You could also use CSS/HTML5 animations: http://slides.html5rocks.com/#css-animation

you could also wrap it in another parentdiv that has position:relative set:

<div class="parent">
  <img class="image" />
</div>

.parent { 
    position:relative; 
}
.image { 
    position:absolute; 
    top:0px; 
    left:0px; 
}
.image:hover { 
    top:-15px; 
}

Give the image an id:

<img id="imgHover" src="" />


 #imgHover:hover { margin-top: -5px; }

Make sure you have this in your html so IE knows how to work properly
