Hyperlinks on website using W3.CSS not working

Question

I am creating a website using a W3 template and using the w3 css file. Something in it is stopping my hyperlinks working. Website something particularly in lines 473 - 490 of the CSS (show below) is causing the issue

 .w3-container:after,
.w3-container:before,
.w3-panel:after,
.w3-panel:before,
.w3-row:after,
.w3-row:before,
.w3-row-padding:after,
.w3-row-padding:before,
.w3-cell-row:before,
.w3-cell-row:after,
.w3-clear:after,
.w3-clear:before,
.w3-bar:before,
.w3-bar:after{
    content:"";
    display:table;
    clear:both
}

I've removed the above code, and that removes the problem - however it introduces a formatting issue instead, so any advice would be gratefully received as my HTML skills are lacking in sorting this out myself.

It seems that you haven't close this div tag :

 <!-- First Grid -->
 <div class="w3-row-padding w3-padding-64 w3-container">
