Border: None vs. Border: 0: Which Is the Best Way to Remove Borders?

CSS Border Syntax: border: none vs. border: 0

Web developers often encounter the need to remove borders from HTML elements. Two common methods for achieving this are border: none and border: 0. However, questions arise regarding their conformance to standards and cross-browser compatibility.

W3C Standard Compliance

Both border: none and border: 0 are considered valid CSS properties. The CSS2 specifications (and subsequent revisions) do not explicitly disallow either form.

Browser Compatibility

In practice, both border: none and border: 0 result in identical output across major browsers. They both effectively remove the border.

Personal Preference

The choice between border: none and border: 0 is ultimately a matter of personal preference. Some developers prefer the conciseness of border: 0, while others find border: none easier to read.

Minimizing Bandwidth

Despite functional equivalence, border: 0 does have a slight advantage in terms of bandwidth consumption. By using the numeric value '0', it requires one less byte than border: none. While this difference is negligible, it could potentially contribute to improved site performance, especially when optimizing every byte counts.

Conclusion

Both border: none and border: 0 are valid and effective methods for removing borders in HTML elements. The choice between the two should be based on personal preference or bandwidth optimization considerations.
