Coders like to use spaces, carriage returns, new lines, tabs and indentation to make their HTML documents human-readable. This helps collaboration and debugging of the HTML document. However, all these features add to the filesize of the resultant HTML document. This structural information is totally ignored by browsers.
This plugin removes spaces, carriage returns, new lines and tabs from your HTML document. You can therefore freely use these features while writing HTML, safe in the knowledge that it will not bloat the final HTML document.
With this plugin you can also mark areas of your HTML template where you want to preserve white space – for example – in areas containing Javascript which needs carriage returns and new lines to function correctly.
HTML comments are not affected by this plugin.

Dashes are punctuation marks that are commonly used in written text. A long dash (—) is known as an em dash, whereas a short dash (–) is known as an en dash.
This plugin converts any whitespace around dashes into smaller hairspaces, to produce a more elegant typographic effect.
Both em and en dashes are recognized.
Look at the following sentence, which uses dashes:
<blockquote>
I love this plugin — and everything about it — because it works so well.
</blockquote>
When this plugin is activated, the sentence would appear like this (with smaller spaces around the dashes):
<blockquote>
I love this plugin — and everything about it — because it works so well.
</blockquote>

This simple but effective plugin converts spaces around dashes (both em and en dashes) into hairspaces.
