How to make image hover in css? - css

Question

I want to change the image from normal to brighter when it's on hover, My code:
<div class="nkhome">
<img src="Images/btnhome.png" />
</div>
.nkhome{
margin-left:260px;
top:170px;
position:absolute;
width:59px;
height:59px;
}
.nkhome a img:hover {
background:url(Images/btnhomeh.png);
position:absolute;
top:0px;
}
Why doesn't work the hover? When my mouse is on it, it shows the first image, not the hover image.

Answer 1

You've got an a tag containing an img tag. That's your normal state.
You then add a background-image as your hover state, and it's appearing in the background of your a tag - behind the img tag.
You should probably create a CSS sprite and use background positions, but this should get you started:
<div>
</div>
div a {
width: 59px;
height: 59px;
display: block;
background-image: url('images/btnhome.png');
}
div a:hover {
background-image: url('images/btnhomeh.png);
}
This A List Apart Article from 2004 is still relevant, and will give you some background about sprites, and why it's a good idea to use them instead of two different images. It's a lot better written than anything I could explain to you.

Answer 2

Simply this, no extra div or JavaScript needed, just pure CSS (jsfiddle demo):
HTML
<a href="javascript:alert('Hello!')" class="changesImgOnHover">
<img src="http://dummyimage.com/50x25/00f/ff0.png&text=Hello!" alt="Hello!">
</a>
CSS
.changesImgOnHover {
display: inline-block; /* or just block */
width: 50px;
background: url('http://dummyimage.com/50x25/0f0/f00.png&text=Hello!') no-repeat;
}
.changesImgOnHover:hover img {
visibility: hidden;
}

Answer 3

You're setting the background of the image to another image. Which is fine, but the foreground (SRC attribute of the IMG) still overlays everything else.
.nkhome{
margin-left:260px;
top:170px;
position:absolute;
}
.nkhome a {
background:url(Images/btnhome.png);
display:block; /* Necessary, since A is not a block element */
width:59px;
height:59px;
}
.nkhome a:hover {
background:url(Images/btnhomeh.png);
}
<div class="nkhome">
</div>

Answer 4

It will not work like this, put both images as background images:
.bg-img {
background:url(images/yourImg.jpg) no-repeat 0 0;
}
.bg-img:hover {
background:url(images/yourImg-1.jpg) no-repeat 0 0;
}

Answer 5

Hi you should give parent position relative and child absolute and give to height or width to absolute class as like this
Css
.nkhome{
margin-left:260px;
width:59px;
height:59px;
margin-top:170px;
position:relative;
z-index:0;
}
.nkhome a:hover img{
opacity:0.0;
}
.nkhome a:hover{
background:url('http://www.prelovac.com/vladimir/wp-content/uploads/2008/03/example.jpg');
width:100px;
height:100px;
position:absolute;
top:0;
z-index:1;
}
HTML
<div class="nkhome">
<img src="http://dummyimage.com/100/000/fff.jpg" />
</div>
​

<a href="Home.html"><img src="http://dummyimage.com/100/000/fff.jpg" onmouseover="this.src='http://www.prelovac.com/vladimir/wp-content/uploads/2008/03/example.jpg'"

Make on class with this. And make 2 different images with the self width and height. Works in ie9.
See this link.

Also you can 2 differents images make and place in the self class name with in the hover the another images.
See example.
.myButtonLink {
margin-top: -5px;
display: block;
width: 45px;
height: 39px;
background: url('images/home1.png') bottom;
text-indent: -99999px;
margin-left:-17px;
margin-right:-17px;
margin-bottom: -5px;
border-radius: 3px;
-webkit-border-radius: 3px;
}
.myButtonLink:hover {
margin-top: -5px;
display: block;
width: 45px;
height: 39px;
background: url('images/home2.png') bottom;
text-indent: -99999px;
margin-left:-17px;
margin-right:-17px;
margin-bottom: -20x;
border-radius: 3px;
-webkit-border-radius: 3px;
