Welcome to a quick tutorial on how to make unselectable text in HTML. So you have a not-so-top-secret website that you want to protect? Stop people from highlighting and copying the text?
There are 2 common ways to create unselectable text:
- In CSS, simply add the
user-select: noneproperty. - In Javascript,
document.getElementById("TARGET").onselectstart = () => false;
That covers the basics, but let us walk through a few more examples in this guide – Read on!

UNSELECTABLE TEXT
All right, let us now walk through how to stop text highlighting in this section, and a few more extra measures.
1) CSS NO TEXT SELECT
<style>
.nohigh {
user-select: none;
-webkit-user-select: none;
-moz-user-select: none;
-ms-user-select: none;
}
.nohigh::selection {
background: transparent;
}
</style>
<span class="nohigh">
You shall not highlight this block of text!
</span>
- As with the above introduction,
user-select: noneis all we need to stop people from highlighting a block of text. - All the
-webkit -moz -msprefix is just-in-case, to maintain cross-browser compatibility. - Lastly,
.nohigh::selection { background: transparent; }is a small trick to further confuse people with a transparent highlight – Should the “main”user-select: nonefails.
2) JAVASCRIPT HIGHLIGHT STOPPER
<script>
window.addEventListener("load", () => {
var all = document.getElementsByClassName("nohigh");
for (let a of all) { a.onselectstart = () => false; }
});
</script>
<div class="nohigh">
You shall not highlight this block of text!
</div>
<div class="nohigh">
Cannot be highlighted.
</div>
This is the Javascript way to prevent text highlighting, just hit return false when the user selects a block of text. But please take note that there is a restriction with this method – Users can still select this block of text by starting the highlighting from somewhere else…
3) TOO MUCH EFFORT, NO PROTECTION. WORTH IT?
Yes, we can combine both CSS and Javascript for the so-called “extra protection”. But it will not stop the advanced users, as there are plenty of ways to bypass that “no text select”:
- Right-click > View source code > Copy.
- Right-click > Inspect element > Copy.
- Save HTML page as > Copy.
- Print as PDF > Copy.
I mean, having a lock is better than none, but is it really worth all the trouble to stop people from copying? You decide for yourself.
