## Here is a short improved example for HTML.
##
syntax "HTML" "\.htm[l]?.j2$"
color brightblue start="<" end=">"
color red "&[^;[[:space:]]]*;"
color yellow ""[^"]*"|qq\|.*\|"
color red "(action|alt|bgcolor|height|href|id|label|longdesc|method|name|onclick|onfocus|onload|onmouseover|rel|size|span|src|style|target|title|type|value|width)="
color magenta start="<!--" end="-->"

## Trailing spaces
color ,green "[[:space:]]+$"

## Jinja templating
color green "\{{2}.*\}{2}"
color green "\{\%.*\%\}"
color brightcyan "(if|endif|for)"
