Typography Tips
Your font size may appear smaller due to the use of em units, which are relative. For example, if your base font size is 20px and you're using 0.75em, a child element's font size would be 15px (20x0.75=15). This cascading effect can lead to progressively smaller font sizes for nested elements. To address this, I've set the text size to 16px for all li elements in the provided jsFiddle.
Images Placement
The CSS section contains unnecessary complexity that could be streamlined by adding a specific class, such as .has-sub-menu, to li elements with sub-menus. By targeting these classes in a more organized manner, you can efficiently define background images for different contexts. Check out the accompanying jsFiddle for implementation details.
Markup Example:
<!-- Sample HTML Structure -->
<div id="nav">
<ul class="menu">
<li><a href="/" title="">Home</a></li>
<li class="has-sub-menu">
<a href="/" title="">Home</a>
<ul class="sub-menu">
<li><a href="/" title="">Home</a></li>
<li><a href="/" title="">Home</a></li>
</ul>
</li>
</ul>
</div>
CSS Styling:
.menu > .has-sub-menu > a {
background-image: url(img-one.png);
}
.sub-menu > .has-sub-menu > a {
background-image: url(img-two.png);
}
Navigation Highlighting
To achieve dynamic highlighting based on the current page, consider assigning unique classes to relevant elements, like products or about, and matching them with body or ancestor element classes. This allows targeted styling for active navigation links while maintaining clarity in your code structure.
HTML Example:
<body class="products">
<div id="nav">
<ul class="menu">
<li class="products"><a href="#">Products</a></li>
<li class="about"><a href="#">About</a></li>
</ul>
</div>
</body>
Corresponding CSS rules can then target specific links based on their associated classes for distinct styling effects.
If CSS alone is insufficient for this functionality, consider incorporating server-side scripting or JavaScript solutions. Additional resources and examples can be found through online platforms like StackOverflow.
