Invisible in Text

The zero-width space has zero visual width. It does not appear as a visible character and does not alter the appearance of surrounding text.

Works Everywhere

Supported across HTML, URLs, plain text files, most social media platforms, and messaging apps that support Unicode.

Line Break Control

Inserting a zero-width space tells browsers and apps that a line break is allowed at that point, helping long words or URLs wrap naturally.

Code Examples

HTML — inline invisible break opportunity

averylongwordthatmightneedawrapbreakhere

HTML — using the semantic  tag (equivalent)

averylongwordthatmightneedawrapbreakhere

URL — break a long URL at a natural point

https://example.com/very/long/path/segment/that/might/need/wrapping

CSS — add as pseudo-element content

.break-hint::after { content: '\200B'; }

About Zero Width Space

The zero-width space (U+200B) is a Unicode character with zero visual width. It is completely invisible to readers but acts as a soft line-break hint for browsers, operating systems, and text renderers. When the rendering engine encounters a U+200B character, it knows it is allowed to break the line at that point if needed — without inserting a visible space or hyphen.

Common use cases include: breaking long URLs or file paths inside constrained UI elements, inserting invisible separators in text for parsing purposes, preventing ligatures between specific letter pairs in typography, and adding hidden markers in text without changing its appearance.

In HTML you can use the entity  or the semantic  tag for the same effect. In CSS, you can inject it via content: '\200B' in a pseudo-element.
