This html shows a red text in Chrome and Firefox:
<font color="rgba(0,0,0,0)">foobar</font>
One would expect transparent font. Is this a browser-bug?
You are confusing HTML and CSS. The color
attribute of the font
element only takes an hex value, such as #000000
which doesn't support transparency. (See https://developer.mozilla.org/en-US/docs/Web/HTML/Element/font#attr-color). rgba(0,0,0,0)
is CSS syntax and can't be used there.
Generally you shouldn't be using the font
element anyway.
