Sometime we need to highlight code with more colours than code than our good syntax highlighter plugin like Crayon Syntax Highlighter for WordPress can do. Here is a guide on nested highlighting in WordPress post with CSS and HTML5 samp element. From our examples readers will understand that such usage is really for few articles with extensive need of manual override. Hence we will suggest to load the CSS for the particular post via WordPress post editor Script input option to inject scripts – standard premium theme like StudioPress Genesis have such option to load the CSS for the particular post.

If we use samp element, we will get exactly code like font effect without any extra CSS. tt is absolute in HTML5 and will return plain text. Modern web crawlers understand everything. To colorize as nested element, we need a set of CSS like this :

 

The above code is “stolen” from regular-expressions.info website as they need to use hugely odd regex and our readers can see the examples of usage on that website. The above CSS has classes :

3. regexnest3,
4. regexplain,
5. regexspecial,
6. regexccopen,
7. regexccspecial,
8. regexccliteral,
9. regexescaped,
10. regexccrange,
11. regexcomment,
12. regexerr,
13. regexmeta,

With HTML5 samp element :

(?<=text), (?<=text), \b\w+(?<!s)\b, \b\w*[^s\W]\b, (?<!ab{2,4}c{3,5}d)test

This is forth one :

\b\w*[^s\W]\b

This is fifth one :

This is sixth one, notice samp class="match" :

\b\w+(?<!s)\b
