How to enlarge pictures in the Knowledge Base

If you want pictures in the Knowledge Base to get larger after a reader points at them with a mouse, do the following. Go to Settings > Knowledge Base settings and edit a particular knowledge base. Next, select Template > Custom CSS and paste:  .help_article_content img {     transition: transform 0.3s; } .help_article_content img:hover {     -webkit-transform: scale(1.25); /* all webkit */     -ms-transform: scale(1.25); /* IE 9 */     -moz-transform: scale(1.25); /* firefox 15 and older */     -o-transform: scale(1.25); /* opera 12 and older */     transform: scale(1.25); }
