A: You can do this with CSS Pseudo Elements .title { color: black; font-weight: normal; } .sub-title { color: black; font-weight: bold; } p { text-decoration: none; position: relative; padding-top: 10px; } p::before { content: ''; position: absolute; width: 100%; height: 2px; background: black; left: 0; bottom: -10px; margin-bottom: 20px; } .under-title { display: block; border-bottom: 2px dotted black; }

A: This can be done simply with CSS by using :hover on the p elements. Here's an example with :hover: .title { color: black; font-weight: normal; } .sub-title { color: black; font-weight: bold; } .under-title { border-bottom: 2px dotted black; } .under-title:hover{ border-bottom:2px dotted red; border-top:2px dotted red; }

And here's the same example with javascript (to illustrate that we can avoid the use of javascript if we don't need it) .title { color: black; font-weight: normal; } .sub-title { color: black; font-weight: bold; } .under-title { border-bottom: 2px dotted black; } .under-title:hover{ border-bottom:2px dotted red; border-top:2px dotted red; }

Here's a jsfiddle that works with no javascript. And one that doesn't. I'll leave this here since it seems to be what you're after. Edit 1: If you want to be able to select the first underlined item and second underlined item independently, you'll have to add a class to the elements, which will do just that. The code would be something like this. .title { color: black; font-weight: normal; } .sub-title { color: black; font-weight: bold; } .under-title { border-bottom: 2px dotted black; } .under-title:hover{ border-bottom:2px dotted red; border-top:2px dotted red; } .under-title.first{ border-bottom:2px dotted red; } .under-title.second{ border-top:2px dotted red; }
