Introduction
The text-overflow
property in CSS is a handy tool for web developers and designers to manage how text overflow is displayed within a container. It works together with other CSS properties, like white-space
and overflow
, to control the appearance of text that exceeds the container’s boundaries. This property helps ensure that text remains readable and well-presented, which is crucial for a positive user experience, especially on responsive websites.
Specification

Description
The text-overflow
property in CSS helps you control how overflowing text is visually indicated to users. It’s useful for fixed-width containers to ensure text doesn’t overflow in an unsightly manner. This property works with other CSS properties, such as overflow
and white-space
, to manage the appearance of overflowing text.
