I found a solution but I think that it is very dumb, I call the class of each category and I change the style of text
like this
.category-2-technique .av-masonry-entry-title.entry-title
{
color: red !important;
}
this solution is so dumb why?
because when i display the blog the title color still black

function custom_excerpt(){
?>
<script>
// trim sentence by 22 words
function trimByWord(sentence,wordcount = 22) {
var result = sentence;
var resultArray = result.split(” “);
if(resultArray.length > wordcount){
resultArray = resultArray.slice(0, wordcount);
result = resultArray.join(” “) + “…”;
}
return result;

jQuery(window).load(function(){
