Image behind the link - html

Question

So I have a menu and on it there is a button with text and I want behind the text to be an image that shows that you are on the page and this is the code:
HTML:
<div id="menu">
<div id="about">About Us</div>
</div>
CSS:
a {
text-decoration:none;
color: white;
background: url(images/hover.png);
width: 100%;
height: 38px;
}
#about {
background: url(images/button.png);
width: 168px;
height: 51px;
font-family: Anivers;
font-size: 20pt;
text-align: center;
color: white;
line-height: 50px;
vertical-align: middle;
margin-top: 1%;
}
So far, so good, except that the image will only show the height and width that coresponds to the size of the text. For instance if I make the text 24pt, the image behind it will grow larger, but if I make it smaller, the image will become smaller and I don't want that. So how do I stop it from happening. I already searched all over the place, sadly I couldn't find similar topic. I hope you can help me :).

Answer 1

If I understand your question correctly you need to add display: block to the <a> element and set height: auto; instead. As for the image it should not scale anymore and I centered an image for demo purposes.

You can accomplish this by displaying your "a" element as a "block". This will allow you to specify the size of the element independent from the size of the font. You can then inherit the width and height of the "#about" css styling if that's the size of "hover.png", or specify your own size based on the actual size of "hover.png" if its different than that stated in "#about", it sounds like 38px for hover.png is what you want as opposed to the 51px height of the #about parent. Without setting "a" as a block, the font size of the text in "#about", the parent element, would rule the overall size of the a element and styling, and your background "images/hover.png" will only provide a background for that size.
Here's what your a element in css would look like with the 38px height, you could also say "inherit" for the height if desired. I tested this and it works:
a {
text-decoration:none;
color: white;
background: url(images/hover.png);
display: block;
width: inherit;
height: 38px;
}
I hope this helps.
