Minifying CSS Stylesheets
Minification (or compression) of a CSS document is the practice of removing unnecessary code without affecting the functionality of the stylesheet.
To minify a CSS, invoke the contextual menu anywhere in the edited document and choose the
Minify CSS action. Oxygen XML Author Eclipse plugin opens a dialog box that
allows you to:
- Set the location of the resulting CSS.
- Place each style rule on a new line.
After pressing OK, Oxygen XML Author Eclipse plugin performs the following actions:
- All spaces are normalized (all leading and trailing spaces are removed, while sequences of white spaces are replaced with single space characters).
- All comments are removed.
Note:
The CSS minifier relies heavily upon the W3C CSS specification. If the content of
the CSS file you are trying to minify does not conform with the specifications, an error
dialog box will be displayed, listing all errors encountered during the
processing.
The resulting CSS stylesheet gains a lot in terms of execution
performance, but loses in terms of readability. The source CSS document is left
unaffected.
Note:
To restore the readability of a minified CSS, invoke
the Format and Indent action from the XML menu, the Source submenu from the contextual menu,
or Source toolbar. However, this action will not recover any of the
deleted comments.
