Hello again. I have (hopefully) a small issue. I'm currently using the most updated version of the Salient theme - in the child version. And when I try adding CSS to the Style.CSS file nothing happens. For example I am currently trying to add the following code into such file but when I update nothing happens.

#logo:hover {
    opacity: 0.5;
}
#logo {
      -o-transition:.5s;
  -ms-transition:.5s;
  -moz-transition:.5s;
  -webkit-transition:.5s;
  transition:0.5s; 
}
::selection {
  background: #ffe000;
}
::-moz-selection {
  background: #ffe000; 
}
#testratt:hover {
    color: #0090ff;
}
#testratt {
    color: #0090ff;
}
#testrat:hover {
    color:#ff009a;
}
#testrat {
    color: #ff009a;
}

Any help? Thanks in advance!
