Emphasizing lines with highlight.js

Question

Is there a way to emphasize lines with highlight.js?

For instance by coloring them differently, changing the background color, or other means.

Answer 1

You can use the HTML5's mark tag.
Let's take this block of Java code as an example:

<pre><code>
View.OnClickListener listener = new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        Log.d(&#x22;TAG&#x22;, &#x22;Clicked!&#x22;);
    }
};
</code></pre>

which will be displayed as following:

and add a gray-on-yellow highlight for a part of the code:

<pre><code>
View.OnClickListener listener = <mark class="highlight-inline">new View.OnClickListener() {
    @Override
    public void onClick</mark>(View v) {
        Log.d(&#x22;TAG&#x22;, &#x22;Clicked!&#x22;);
    <mark class="highlight-inline">}</mark>
};
</code></pre>

<style type="text/css">
.highlight-inline {
    background:yellow;
    color:gray;
}
.highlight-inline span {
    background:inherit;
    color:inherit;
}
</style>

which will result as:
