i'll have a try on my first question.
This is a problem, I had a few times, but don't exactly know, how to solve it:
I have a semitransparent background image (eg transparent rounded corners) which also as a gradient background color. (In this example it's a button for a dropdown navigation: When you hover the button, nav-list appears.)
Here's the code:
<div id="top-navi"><a id="top-navi-button" href="#" >Navigation</a>
<ul>
<li><a href='#'>bla</a></li>
<li><a href='#'>blubb</a></li>
</ul>
</div>
CSS:
#top-navi {
position: fixed;
top: 0px;
left: 6%;
z-index: 1000;
}
#top-navi a#top-navi-button {
float: left;
width: 130px;
height: 20px;
padding: 5px 10px 5px 20px;
background: url(../img/top-navi-button.png) no-repeat;
color: #FFF;
font-size: 120%;
text-decoration: none;
}
#top-navi a#top-navi-button:hover,
#top-navi a#top-navi-button:focus {
text-decoration: underline;
}
The text on the button is white. Because i want to make the site accessible, I don't put the text on the image, but write it in html (so screenreaders can read it) and style it white. This works pretty well until here.
Now, I want to make it even more accessible, so you can use all functionality, even if images are deactivated. If I do this (eg with FF developer toolbar) the background image disappears and you can't see the white text anymore.
Now, if I give the link a background-color (in addiotion to the image) it laps over the transparent corners. I also tried to put the text in a <span>
and give it a background color, but as my image has a gradient, you see the background-color of the span then.
Any ideas how to solve that? Thank you very much in advance!

You need an extra image for the non-transparent gradient part of the image. When you add the span
to the link you can style the span to have the solid background and a fallback color.
+------------------------------------------------+
| a: Gradient and shadow |
| +---------------------------------------------+|
| | a > span: Solid gradient + background color ||
| +---------------------------------------------+|
+------------------------------------------------+
So, HTML:
<a id="top-navi-button" href="#"><span>Navigation</span></a>
And CSS something like:
a#top-navi-button {
background: url(top-navi-button.png) no-repeat;
}
a#top-navi-button span {
background: url(top-navi-solid_gradient.png) #00F;
}
Please note that if you want to create an accessible site you should also consider offering keyboard navigation . Right now you can't use the Tab
key to select any of the menu items.
