When you create a website, you can customize the text color with color property. It will change the color of your text as well as the link underline color. But what if you want to set the link underline a different color from the text's color? There are various ways to do that. In this tutorial, I will show you how to use box-shadow property to customize the link underline.
To start, you create an anchor element.
a(href="/") This is a link
In CSS, you disable the text-decoration property with none value. The reason we set the text color black is that it won't change after the link is activated. You use tomato color for the underline. We need to create space between the text and the underline. We set the padding of the link 4px.
a {
text-decoration: none;
color: black;
padding: 4px;
box-shadow: 0 3px tomato;
}
You can see that your link underline has a new color. But it doesn't give the user any feedback when they hover over the link. We will make it responds to when the user interacts with the link.
a {
text-decoration: none;
color: black;
padding: 4px;
box-shadow: 0 3px tomato;
&:hover {
background: tomato;
color: white;
box-shadow: 0px 10px 10px 0px gray;
}
}
The link will be white with tomato background. It also had a gray shadow under when you hover the link. But it's quite lagging. To make it smoother, we will use transition property.
a {
transition: background 0.1s, box-shadow 0.3s, color 0.1s;
}
The text color and the background will change in 0.1s while the box-shadow is in 0.3s. It is smoother now. You can change the transition duration to any value you want.
