Will dynamic CSS usage rules be come true?

[onkenut]

it just like this:

.text {
text-align: right;
font-size: 14pt;
}
<div class="text"> </div>，
<div class="text(null,20)"> </div>,
<div class="text(center,null)" > </div>,
<div class="text(center,20)"> </div>,
<div class="text(font-size=20)"> </div>
