Apparently, CSS code embedded in TWiki cannot handle tabs. The Chrome Developer Console shows the affected classes as empty.

This issue was discovered when previously working CSS/HTML code was copied from a .html file and pasted into a TWIki page. The CSS did not work in the TWiki page until tabs were converted to spaces.

Problem Code: Example

Consider the following CSS code:

<style type="text/css">
.MainBackground1 {
   background-image: url('%PUBURLPATH%/%WEB%/%TOPIC%/DocumentStack1.jpg');
   background-repeat: no-repeat;

A page that contains

<div class="MainBackground1"> 

should show the specified background gif behind the content between the div tags. It does not.

See VickiBrownCSS1 for live code.

The Chrome Developer console insists that the definition of class MainBackground1 is empty.

Working Code: Example

This CSS code works:

<style type="text/css">
.MainBackground1 {
  background-image: url('%PUBURLPATH%/%WEB%/%TOPIC%/DocumentStack1.jpg');
  background-repeat: no-repeat;

See VickiBrownCSS2 for live code.

The only difference is that the first example indents with tabs while the second indents with spaces.
