Word Wrapping in CSS/JS: A Cross-Browser Solution
The challenge of wrapping long strings of text within predetermined DIV widths without scrolling has long plagued web developers. To address this, various approaches have been explored, each with its own limitations.
- Overflow techniques like "overflow: hidden/auto/scroll" restrict text visibility and allow scrolling, which is not desired in this scenario.
- Injecting - into the string requires JavaScript or server-side modifications, but may disrupt copying and pasting and is not consistently supported across browsers.
- Measuring text width via hidden elements is computationally expensive and can lead to frozen sites, especially for extensive text bodies.
- Monospace fonts can disrupt width calculations and limit text styling.
Despite promising candidates like "word-wrap: break-word" and "
Eureka! CSS to the Rescue
Finally, a breakthrough emerges in the realm of CSS:
.wordwrap {
white-space: pre-wrap; /* css-3 */
white-space: -moz-pre-wrap; /* Mozilla, since 1999 */
white-space: -pre-wrap; /* Opera 4-6 */
white-space: -o-pre-wrap; /* Opera 7 */
word-wrap: break-word; /* Internet Explorer 5.5+ */
}
Utilizing this CSS rule, developers can seamlessly achieve cross-browser word wrapping without the pitfalls of previous methods. Additionally, you can employ the "word-wrap: normal;" rule to revert to default wrapping behavior.
This solution elegantly addresses the challenge of word wrapping, empowering developers to display long URLs and other uninterrupted text strings in an aesthetically pleasing and browser-compatible manner.

What is 'render-blocking CSS'?
Jun 24, 2025 am 12:42 AM
CSS blocks page rendering because browsers view inline and external CSS as key resources by default, especially with imported stylesheets, header large amounts of inline CSS, and unoptimized media query styles. 1. Extract critical CSS and embed it into HTML; 2. Delay loading non-critical CSS through JavaScript; 3. Use media attributes to optimize loading such as print styles; 4. Compress and merge CSS to reduce requests. It is recommended to use tools to extract key CSS, combine rel="preload" asynchronous loading, and use media delayed loading reasonably to avoid excessive splitting and complex script control.

CSS: When Does Case Matter (and When Doesn't)?
Jun 19, 2025 am 12:27 AM
In CSS, selector and attribute names are case-sensitive, while values, named colors, URLs, and custom attributes are case-sensitive. 1. The selector and attribute names are case-insensitive, such as background-color and background-Color are the same. 2. The hexadecimal color in the value is case-sensitive, but the named color is case-sensitive, such as red and Red is invalid. 3. URLs are case sensitive and may cause file loading problems. 4. Custom properties (variables) are case sensitive, and you need to pay attention to the consistency of case when using them.
