Patapage allows the use of HTML in contributions, comments and other buttons and functions.
However, we do not allow all HTML tags, as that would result in a XSS paradise, but we tried to allow a quite expressive set.
Some tags are not allowed at all, some are allowed with restriction, some are free.
all style attributes are allowed except for those that require the url() parameter.
allowed : style="background-color: #f0f0f0;"
forbidden : style="background-image: url(test.png);"
Some additional information:
<!-- comments --> comments will be removed. href or src parameters are allowed on <a> and <img> tags only; and must refer to a valid http or https url. with and height parameters must be numeric or percentage.
Eventually unclosed, but valid, tags will be closed automatically. Unknows tags will be removed.
