javascript - Property text-rendering doesn't exist : optimizelegibility -

-

using code @ web browsers:

.h1,.h2,.h3,.h4,.h5,.h6{margin:1.25em 0 0.2em;text-rendering:optimizelegibility}

on wc3 validation getting error

property text-rendering doesn't exist : optimizelegibility

and seems property having issue android here

is property no longer exists now?

it never existed; text-rendering part of svg, not css.

the text-rendering property svg property not defined in css standard. however, gecko , webkit browsers let apply property html , xml content on windows, mac os x , linux.

in other words, text-rendering has effect on non-svg elements @ nonstandard. according mdn page, it's not supported anyway (internet explorer , opera don't understand it) , implementations exist have known issues.

it might best avoid altogether.
