I find that when I upload Styled HTML to Google Docs, eg. with CSS
.underline { text-decoration: underline; }
.del { text-decoration: line-through; }
mark { background: yellow }
None of these will take effect. However if I use CSS produced when downloading a Google Docs as HTML like
.c9 {
text-decoration:underline;
}
It works. Can I say that Google does not take into considerations any CSS?
