 ! Overriding Theme Settings
 
-Note that custom stylesheets are applied independently to the theme stylesheets. This means that it is frequently necessary to use CSS specificity to reliably override settings within the theme. This means ensuring that the CSS rule in your custom stylesheet is more specific than the theme rule that you are overriding. "More specific" generally means using more CSS rules. So, `html body.tc-body` is more specific than `body.tc-body`.
+Custom stylesheets are applied independently from theme stylesheets. Therefore, it is often necessary for the css rules in your custom stylesheet to be more specific than those of the theme you want to override. For example, `html body.tc-body` is more specific than `body.tc-body`.

 If you wish to use macros and transclusions in your stylesheets you should instead use the default WikiText type `text/vnd.tiddlywiki`. This allows full WikiText processing to be performed. Here is an example:
 
 ```
-\rules only filteredtranscludeinline transcludeinline macrodef macrocallinline
+\rules only filteredtranscludeinline transcludeinline macrodef macrocallinline html
 
-body.tc-body pre {
+<pre>body.tc-body pre {
 	<<box-shadow "inset 0 1px 0 #fff">>
 }
+</pre>
 ```
 
 The `\rules` pragma at the top of the tiddler restricts the WikiText to just allow macros and transclusion. This avoids mistakenly triggering unwanted WikiText processing.
 
+A stylesheet tiddler is processed such that it is wikified first and then its text extracted so as to apply only css. Any html tags you will use in your stylesheet are thus eventually ignored. For example, html elements generated by the reveal widget will not affect the output. As in the example above, you could also wrap css rules in `<pre>` tags to display them as a codeblock which will, however, still correctly wikify the inner macro.

 !! Stylesheet Macros
 
 Several globally available macros are provided that are helpful in constructing stylesheets. See [[$:/core/ui/PageStylesheet]] for the definitions of these macros.
