syntaxhighlighter how to change the color of comment

问题

I am new to using syntaxhighlighter. I am using there latest version 3.0.83. Can some one help how to customize the color of comments, header, etc ?

I am using < pre class="brush: c"> for coding style.

回答1:

The easiest solution would be to override the CSS rules for comments, but they're marked as !important so you have to do a little extra work.

Open your shBrushCpp.js file. Down towards the bottom there's a set of regular expression rules paired with a css property. Those values correspond to class names in shThemeDefault.css (or whatever theme you're using).

Copy your theme file to something like shThemeCustom.css or whatever you want. Include this file on your page instead of the original theme. From here, you can change whatever you want. Just reference the CSS rules from the brush file against your custom theme to know what needs to be changed.

In case you don't have full control over the .css or .js files, as is my case (since I followed these instructions here and am using Alex Gorbatchev's hosted files instead), there is still a way to override the !important parameter.

You can customize any of the settings shown here (http://agorbatchev.typepad.com/pub/sh/3_0_83/styles/shThemeDefault.css), for example, as follows:

With the default theme, this HTML...

<pre class="brush:cpp" title="test code">
int myFunc()
{
  //do something
  return 1;
}
</pre>

...yields this result:

Looking here (http://agorbatchev.typepad.com/pub/sh/3_0_83/styles/shThemeDefault.css), I can see the parameters I am currently using. For example, it contains:

.syntaxhighlighter {
  background-color: white !important;
}
.syntaxhighlighter .line.alt1 {
  background-color: white !important;
}
.syntaxhighlighter .line.alt2 {
  background-color: white !important;
}
...
.syntaxhighlighter .comments, .syntaxhighlighter .comments a {
  color: #008200 !important;
}

In order from top to bottom, as shown just above, my header background color is white and my alternating code lines 1 and 2 are both white. Comments are green (#008200). Let's change all of that. Add the following code to your blogger template, at the very end of your header, just above </head>:

<style type='text/css'>
  .syntaxhighlighter {
    max-height: 550px;
    background-color: #ff0000 !important;
    overflow-y: auto !important;
    overflow-x: auto !important;
  }
  .syntaxhighlighter .line.alt1 {
    background-color: #99ff99 !important;
  }
  .syntaxhighlighter .line.alt2 {
    background-color: #99ff99 !important;
  }
  .syntaxhighlighter .comments, .syntaxhighlighter .comments a {
    color: #000082 !important;
    font-weight: bold !important;
  }
</style>

Now, I have set my max-heightto 550 pixels (make a really long code block and you'll see it constrained to this height now, with a vertical slider to see it all), my header background color is red (#ff0000), my code background color (both alternating lines) is light green (#99ff99), and my comments are blue (#000082) and bold. Follow this format to customize anything you see in your .css theme file--example, for me, here: http://agorbatchev.typepad.com/pub/sh/3_0_83/styles/shThemeDefault.css.

Here is my final result--very different from the default look above:

Note that the font-weight parameter I set is simply a CSS styling you can apply. Many other options exist. See here: http://www.w3schools.com/cssref/pr_font_weight.asp.
