双下划线效果CSS

Question

I have this code from the Hover.css pack :

.hvr-underline-from-left{
            display: inline-block;
            vertical-align: middle;
            -webkit-transform: translateZ(0);
            transform: translateZ(0);
            box-shadow: 0 0 1px rgba(0, 0, 0, 0);
            -webkit-backface-visibility: hidden;
            backface-visibility: hidden;
            -moz-osx-font-smoothing: grayscale;
            position: relative;
            overflow: hidden;
        }
        .hvr-underline-from-left::before {
            content: "";
            position: absolute;
            z-index: -1;
            left: 0;
            right: 100%;
            bottom: 0;
            background: #0F9E5E;
            height: 0.3em;
            -webkit-transition-property: right;
            transition-property: right;
            -webkit-transition-duration: 0.2s;
            transition-duration: 0.2s;
            -webkit-transition-timing-function: ease-out;
            transition-timing-function: ease-out;
        }
        .hvr-underline-from-left:hover::before, .hvr-underline-from-left:focus::before, .hvr-underline-from-left:active::before {
            right: 0;
        }

What this does is that it adds a buttom border to a button that appeares from the left on hover.

But the effect i want is this, but multible times. So this should be added multible times with 0.1s delay every time, and an other color. How would i do this? I tried using ::before(n) but it didn't work.

You can use after pseudo class to get the double underline effect.

//same as before class except for transition delay and bottom position you can adjust that as needed

        .hvr-underline-from-left::after {
        content: "";
        position: absolute;
        z-index: -1;
        left: 0;
        right: 100%;
        bottom: 10px;
        background: #0F9E5E;
        height: 0.3em;
        -webkit-transition-property: right;
        transition-property: right;
        -webkit-transition-duration: 0.1s;
        transition-duration: 0.1s;
        -webkit-transition-timing-function: ease-out;
        transition-timing-function: ease-out;
    }

  // on hover effect for after same as before class. 
    .hvr-underline-from-left:hover::after, 
    .hvr-underline-from-left:focus::after, 
    .hvr-underline-from-left:active::after {
        right: 0;
    }



     //to add more

    .hvr-underline-from-left .hvr-underline-from-left{
    position:absolute;
    height:100%;
    width:100%;
    background:transparent;
    top:0;
    left:0;
    z-index:1000;
    }
    .hvr-underline-from-left .hvr-underline-from-left:after{
    bottom:20px;
     -webkit-transition-duration: 0.3s;
    transition-duration: 0.3s;
    }
    .hvr-underline-from-left .hvr-underline-from-left:before{
    bottom:30px;
     -webkit-transition-duration: 0.3s;
    transition-duration: 0.3s;
    }

// and div tags look like this 
<div class="hvr-underline-from-left">
   <div class="hvr-underline-from-left">
    </div>
</div>

****Please be careful once you give the inner container z-index and bring it to the front with 100% height and width any elements inside the main container might not be clickable.

Alternatively You can use css animation keyword for getting this multiple times underline effect with different color.and Adjust time according to your need. eg

 .hvr-underline-from-left{ display: inline-block; vertical-align: middle; -webkit-transform: translateZ(0); transform: translateZ(0); box-shadow: 0 0 1px rgba(0, 0, 0, 0); -webkit-backface-visibility: hidden; backface-visibility: hidden; -moz-osx-font-smoothing: grayscale; position: relative; overflow: hidden; } .hvr-underline-from-left::before { content: ""; position: absolute; z-index: -1; left: 0; right: 100%; bottom: 0; height: 0.3em; -webkit-transition-property: right; transition-property: right; -webkit-transition-duration: 0.2s; transition-duration: 0.2s; -webkit-transition-timing-function: ease-out; transition-timing-function: ease-out; } .hvr-underline-from-left:hover::before { animation:colorUnderline 2s; animation-fill-mode: forwards; } @keyframes colorUnderline{ 0%{ right:100%; background: #0F9E5E; } 25%{ background: #0F9E5E; right:0; } 26%{ background: #8e44ad ; right:100%; } 50%{ background: #8e44ad ; right:0; } 51%{ background: #e74c3c ; right:100%; } 75%{ background: #e74c3c ; right:0; } 76%{ background: #f1c40f ; right:100%; } 100%{ right:0; background: #f1c40f ; } } 

 <body> <div class="hvr-underline-from-left">Test</div> </body>
