Question

I am currently trying to make a custom underline with border-bottom. However, currently the underline is going all the way of my block-element (whole page).

I’d prefer to have it being only 50px longer than my headline (however the text is flexible and I do not know the length).

Can I do this without adding another <span> tag within the <h2> somehow? I do not wannt to add a <span> element to each <h2> just to change my design.

Current HTML is:

<h1>My title</h1>

CSS:

h1 {
    font-size: 18px;
    color: #b62525;
    border-bottom: 2px solid #c68181;
}

Is it possible to adjust the border-bottom length to my text length? (e.g. behave like inline element for border, but like block for newlines, padding and margin)

Answer 1

Using display: inline-block works, the only caveat being that the content after the <h1> tag must be the full width of the container element. The other solutions here also assume this. You can also use display: inline (supported by older browsers), but inline-block allows for setting of explicit widths, should you need it.

Here’s a JSFiddle

CSS

h1
{
    display: inline-block;
    padding-right: 50px;
    border-bottom: 1px dotted #888;
}
