Link retains underline even after text-decoration:none - css

Question

I am making a navbar for a website made via GatsbyJS. I am attempting to style the links in the navbar such that they do not have an underline.
I have already set the link to not have any text decoration--when I inspect the element in my browser, it even shows the "text-decoration: none" property. I have also confirmed that my CSS is influencing the object--I can change the color of the text, for example, it is only the text-decoration which I cannot influence.
CSS:
.nav {
background: #fd8;
}
.nav ul {
text-align: center;
border: 1px solid #000;
}
.nav ul li {
display: inline-block;
padding: 8px 10px;
margin: 0;
}
.nav ul li a {
color: #221;
text-decoration: none;
}
html + js:
...
import { Link } from "gatsby"
import styles from "./navbar.module.css"
...
<nav className={styles.nav}>
<ul>
<li>
<Link style={{ textDecoration: 'none' }} to="/about">
About
</Link>
</li>
EDIT: the inline styling with textDecoration was a product of some fiddling I was doing prior to posting this question and was not present until recently. Removing it has no effect on the issue.
Rendered HTML by request:
<nav class="navbar-module--nav--25Dcz">
<ul>
<li>
About
</li>
...
</ul>
</nav>

Answer 1

I have discovered that the errant underline was actually a 1px box-shadow, probably from some global style I can't find associated with the Gatsby Typography plugin.

Answer 2

When you say .nav you want to select a class by that. And as I see, in your html,
nav (<nav...) is a tag with a class navbar-module--nav--25Dcz
So if you change your CSS to:
(Remove the period character . from .nav)
nav {...}
nav ul {...}
nav ul li {...}
nav ul li a {...}
It should work fine.
Also, take a look at Styled Components: https://www.styled-components.com/ which let you write CSS in JS and use similar features from preprocessors like Less and SASS.
Hope this helps!

Your issue is that you're using a class selector (.nav) when you should be using a tag name selector instead. Changing to nav ul li a{text-decoration:none} should fix your issue. If that doesn't work, then you probably have some CSS with higher precedence somewhere that is overriding it.

So for those still searching for an answer. It's really a BUG. At least with <ul>, <li> tags and their nesting. There's just one bypass, and even that has a bit of a limitation. So here's a sample with a fixed (removed) underline and it contains notes also on what to add, what to avoid.
https://stackblitz.com/edit/keep-remove-underline-from-nested-li-item?file=index.html [working text decoration removal]
the solution is:
need to use inline-block for <ul>, set vertical top align and 100% width
avoid to use white-space nowrap

Answer 5

I tried everything to remove it, then after reading this I remembered that I added what in the link https://www.gatsbyjs.org/docs/typography-js/
Icones was underlined, anything that will be was underlined
nothing worked until I removed that.

Answer 6

I can't explain why, but when I referenced a class that was LESS specific I was able to get the text decoration to go away with text-decoration none. So if you have a less specific wrapper class try targeting the links with that
.wrapper a {
text-decoration:none;
}

Answer 7

You can select the global a tag or be specific, and after text decoration, add !important. That will override any default styling that gatsby is imposing.
.nav ul li a {
color: #221;
text-decoration: none !important;
}
