问题 I figured out how to make an underline under a part of my navigation bar when I am hovering over the word.

Thanks :) *{ margin:0; padding:0; border:0; } .topnav { background-color: purple; overflow: hidden; } .topnav a { float: left; color: #f2f2f2; text-align: center; padding: 14px 16px; text-decoration: none; font-size: 17px; position:

问题 When hovering a link I want it to get an underline. The underline should be 2px strong and 4px below the text. With text-decoration: underline I get a 1px strong line which is 4px below. (Distances vary by font) If I write border-bottom: 2px solid #000; I get a 2px line which is about 10px below the text. How can I decrease the distance between the text and the border? padding-bottom: -6px does not work. Any negative value with padding-bottom does not work. Or how can i get the underline to

问题 Is there a way to control the position of the underline in text-decoration: underline? <a href="#">Example link</a> The example above has an underline by default...is there a way to nudge that underline down by a few pixels so that there is more space between the text and the underline? 回答1: The only way to do that is to use a border instead of an underline. Underlines are notoriously inflexible. a { border-bottom: 1px solid currentColor; /* Or whatever color you want */ text-decoration: none

问题 I'm trying to emulate this effect via CSS: The reason this is an issue is because it needs to be re-usable. The red underline's size should be dictated by the text length, but also overflow its container in a predictable manner, e.g.: <div> <h1>This</h1> <h1>Cool</h1> <h1>Effect</h1> </div> The red underline should extend outside the div by 10px on the left, and then also overflow the text itself by roughly 50px on the right. So, all told, the red line is +60 pixels wider than the text itself

问题 I'm trying to figure out how to create a custom background effect for text. In other words, how can I make something like this: 回答1: Use the <mark> element and tweek the line-height mark { display: inline-block; line-height: 0em; padding-bottom: 0.5em; } <h1><mark>Lorem ipsum</mark></h1> 回答2: For these I usually use an SVG pixel (a 1x1 stretchable HTML-encoded SVG with a fill color) that we can manoeuvre anyway we want: h1 { background: url("data:image/svg+xml;charset=utf8,%3Csvg version='1.1
