Custom HTML Tags
mPDF uses a number of custom HTML tags (see HTML Control Tags - Overview).
In addition to those, the custom tags <ttz> <tts> and <tta> are reserved for use internally within
the mPDF program to denote the core symbol, dingbat and arial characters.
Invalid HTML?
(mPDF ≥ 2.2)
If you want to hide mPDF custom tags from a browser, enclose any mPDF code within:
<!--mpdf .. anything you want to write ... mpdf-->
As these are the standard comment tags recognised by every browser, this will create valid HTML which should output
correctly in any circumstances. mPDF will strip away the <!--mpdf tag and any
following spaces, and the $mpdf--> tag and any preceeding spaces, and process all
enclosed code.
Note: Almost all mPDF custom tags are self closing e.g. <pagebreak />. If you do not use
self-closing tags, the HTML may not show correctly in a browser unless you hide the tags in special comments as above.
Most browsers will ignore (self-closing) tags that are not recognised, but <htmlpageheader> and
<htmlpagefooter> are different, as they contain innerHTML e.g.
<htmlpageheader name="phname">HTML code in here</htmlpageheader>
The enclosed innerHTML will be output by a browser, so you need to hide it; either use the special comment tags as above, or an alternative is to use CSS, e.g. add to your stylesheet
htmlpageheader { display : none; }
htmlpagefooter { display : none; }
Yet another way is to use in-line CSS:
<htmlpageheader name="phname" style="display: none;">HTML code in here</htmlpageheader>
