	as follows.		as follows.

	~~===Pros of HTML===~~
	~~# In-line HTML formulae always align properly with the rest of the HTML text.~~
	# The formula’s background and font size match the rest of HTML contents and the appearance respects CSS and browser settings while the typeface is conveniently altered to help you identify formulae.
	~~# Pages using HTML code for formulae will load faster and they will create less clutter on your hard disk.~~
	~~# Formulae typeset with HTML code will be accessible to client-side script links (a.k.a. scriptlets).~~
	# The display of a formula entered using mathematical templates can be conveniently altered by modifying the templates involved; this modification will affect all relevant formulae without any manual intervention.
	# The HTML code, if entered diligently, will contain all semantic information to transform the equation back to TeX or any other code as needed. It can even contain differences TeX does not normally catch, e.g. <code><nowiki>{{math\|''i''}}</nowiki></code> for the [[w:imaginary unit\|imaginary unit]] and <code><nowiki>{{math\|<VAR>i</VAR>}}</nowiki></code> for an arbitrary index variable.

	~~Traditionally, math~~ markup goes inside the ~~[[Help:XML-style tags\|XML-style tag]]~~ math: <code><nowiki><math> ... </math></nowiki></code>~~.

	~~However, one can also use parser function [[mw:Help:Magic_words#Miscellaneous\|#tag]]: <code><nowiki>{{#~~tag~~:math\|..~~.}}</nowiki></code>; this is more versatile: the wikitext at the dots is first [[Help:Expansion\|expanded]] before interpreting the result as TeX code. Thus it can contain parameters, variables, parser functions and templates. Note however that with this syntax double braces in the TeX code must have a space in between, to avoid confusion with their use in template calls etc. Also, to produce the character "\|" inside the TeX code, use <nowiki>{{!}}</nowiki>.<ref>This requires the wiki to have the [[Template:!]] containing "\|", as many wikis do, see e.g. also [[w:Template:!]].</ref>

	Similar to HTML, in TeX extra spaces and newlines are ignored.		Similar to HTML, in TeX extra spaces and newlines are ignored.
