Truncating Text in HTML Tags Using Ellipsis
In a world of responsive web design, it's common to encounter situations where content may exceed the available width of an element, resulting in undesired text wrapping or breakage. For headings (h2) with dynamic text lengths, this can present an aesthetic challenge.
Problem:
How can you elegantly truncate the content within an h2 tag and add an ellipsis (...) when the text exceeds the available width of the screen or container?
Solution:
Fortunately, modern web browsers provide a simple and cross-browser solution using CSS. By adding the following CSS class to the h2 tags, you can achieve the desired effect:
<code class="css">.ellipsis {
white-space: nowrap;
overflow: hidden;
text-overflow: ellipsis;
-o-text-overflow: ellipsis;
}</code>
This CSS class applies the following settings:
- white-space: nowrap prevents the text from wrapping to a new line.
- overflow: hidden hides any content that exceeds the available width.
- text-overflow: ellipsis and -o-text-overflow: ellipsis (for Opera) display an ellipsis (...) at the end of the truncated text.
Using this CSS class, the h2 tag will gracefully truncate its content and add an ellipsis when it becomes too wide for its container. Note that this solution is valid for all major browsers as of writing, with the exception of Firefox 6.0. For support in earlier versions of Firefox, consider the solution provided in the linked question mentioned in the answer.
