I have a li and wanted to get the elements that are written MARKED below. But I used the nth-of-type, it works to get the 4 element always, but I could not get the next one. Could someone help me to always get 1 after the first item where it is marked marked?
ul li&:nth-of-type(1){color: red;}
ul li&:nth-of-type(4n){color: red;}
<ul>
<li class="col-sm-3">number MARCADO</li>
<li class="col-sm-3">number</li>
<li class="col-sm-3">number</li>
<li class="col-sm-3">number MARCADO</li>
<li class="col-sm-3">number MARCADO</li>
<li class="col-sm-3">number</li>
<li class="col-sm-3">number</li>
<li class="col-sm-3">number</li>
<li class="col-sm-3">number MARCADO</li>
<li class="col-sm-3">number MARCADO</li>
<li class="col-sm-3">number</li>
<li class="col-sm-3">number</li>
<li class="col-sm-3">number</li>
<li class="col-sm-3">number MARCADO</li>
<li class="col-sm-3">number MARCADO</li>
<li class="col-sm-3">number</li>
</ul>
