HTML Attributes

HTML tag Attributes (in-line) supported

Example of an HTML attribute: <div align="center">

mPDF supports attribute values in single or double quotes e.g. <div align="center"> or <div align='center'>

Minimised attributes are not supported e.g. <input type="checkbox" disabled />

XHTML specification is recommended for best compliance with mPDF.

Note: The attributes $class, $id and $style are supported on most HTML tags: see Supported CSS for details.

HTML, BODY and ALL recognised tags	lang*	LANGUAGE-COUNTRY CODE *
HTML, BODY and ALL recognised tags	dir	rtl \| ltr (mPDF ≥ 6.0)
HTML, BODY	dir	rtl \| ltr (mPDF ≥ 5.0)
P, DIV	align	left \| center \| right \| justify
TABLE	border	1 \| 0
	width	LENGTH
	align	left \| center \| right \| char char was added in mPDF 5.7
	char	Used in conjunction with `align="char"`. Default if omitted is period `"."` Non-ASCII characters can be defined with HTML entities e.g. `·` or `·` As per HTML 4 spec. Added mPDF 5.7
	bgcolor	#rrggbb
	cellSpacing	LENGTH
	cellPadding	LENGTH
	(repeat_header)	1 (removed from mPDF ≥ 5.4; use `<thead>`)
	autosize	FLOAT The value ≥ 0 shrinks a table to fit if width is too small to allow complete words to fit. The value (must be ≥1) determines the maximum allowable factor to shrink i.e. `autosize="2"` will allow the font-size to be reduced to a minimum of 1/2 the original size. A value of 1 prevents automatic resizing of the table. (custom attribute)

* $lang is only recognised when the variable $useLang is set to true (Default is true)

Note: Table page-break-inside, autosize values and rotate are only respected for that set on first level table of nested tables

Note: Attributes like nowrap, disabled, multiple, readonly, selected and checked are only supported in their formal/long form i.e. selected="selected"

Note: LANGUAGE-COUNTRY CODE accepts codes for $lang according to the HTML specification. e.g. "en", "en-US", "fr", "zh-HK". The settings for these languages are defined in the \Mpdf\LangToFont class. Other codes for character sets (or codepages) are recognised - see \Mpdf\Mpdf::__construct().

Changelog
