formatting reasons, such as indentation and wrap.

</p>
|

|

<p>
|
|
|
|
|
This can greatly improve readability for editors who are hand-editing
|
|
|
|
|
the HTML, but is by no means necessary as HTML Purifier has already
|
|
|
|
|
fixed all major errors the HTML may have had. Tidy is a non-default
|
|
|
|
|
extension, and this directive will silently fail if Tidy is not
|
|
|
|
|
available.

<p>

If you are looking to make the overall look of your page's source
|
|
|
|
|
better, I recommend running Tidy on the entire page rather than just
|
|
|
|
|
user-content (after all, the indentation relative to the containing
|
|
|
|
|
blocks will be incorrect).
