I am new to javascript and jquery and... so I have question How can I access my font-size in this set of selectors in my css using javascript code:
.bt-menu ul li a
{
display: block;
outline: none;
color: transparent;
text-align: center;
text-decoration: none;
font-size: 0px;
}
.bt-menu ul li a:before
{
color: #fff;
font-size:35px;
opacity: 0.5;
-webkit-transition: opacity 0.2s;
transition: opacity 0.2s;
}
In my java script I tried this :
document.querySelector(".bt-menu ul li a:before").style.fontSize="12px";
but it didn't work , I tried
document.querySelector(".bt-menu ul li a").style.fontSize="12px";
it worked but it's not what I need, because with the :before it didn't work and I need to access the font size in bt-menu ul li a:before , can anyone guide me?
