I made a base with a class system for a certain color to an element. Even putting the rule he does not accept. Example:
<span class="mc c0 s1">Olá Mundo :D</span>
In CSS it looks like this:
.mc .c0 {
color: red;
}
.mc .s0 {
font-style: italic;
}
And you're not applying the c0 and s0 rule together or separate. even with !important
together.
