I have 3 services in a row, If you hover over each services title text, the underline gets longer under the corresponding title, What I want to do is make it so when you hover over the button or the title text, the line gets longer.
I would prefer a css solution if possible, I have tried the + (maybe wrongly) but it does not seem to be working for me
<div class="row ">
  <div class="col-xl-3 col-lg-4 ">

  <div class="col-xl-3  col-lg-4 ">
