Emphasis Description

This plugin enables three different ways of highlighting. Each one maps to a css class attribute meaning the style can be freely defined in the style sheet. This is similar to hilited and highlight with the difference that it allows three degrees of highlighting. -stefan

::text::

:::text:::

::::text::::

Point your Plugin Manager to this URL: emphasis-plugin-2007-02-09.zip. This automatically downloads, unzips and installs the plugin.

To style the three different highlights set up your CSS like this:

span.emphasis1 {font-weight:bold; color:#ff0033}
span.emphasis2 {font-weight:bold; color:#009700}
span.emphasis3 {font-weight:bold; color:#ff1a55}
