Border: None or Border: 0? Which CSS Property Should You Use?

Understanding 'border: none' vs. 'border: 0'

In CSS, there are two ways to remove the border of an element: 'border: none' and 'border: 0'. Which one should you use?

W3C Standards and Browser Compatibility

Both methods conform to W3C standards. They are equivalent in terms of rendering results across all browsers.

Personal Preference and Optimization

The choice between 'border: none' and 'border: 0' largely boils down to personal preference. Some developers prefer 'border: 0' for its brevity, while others find 'border: none' more legible.

From an optimization standpoint, 'border: 0' has a slight advantage in terms of bandwidth savings. However, this difference is negligible and shouldn't be a major factor in your decision.

Recommending Practices

Ultimately, the choice between 'border: none' and 'border: 0' is a matter of personal preference. If optimizing bandwidth is a priority, 'border: 0' may be slightly better. However, most developers find 'border: none' more intuitive and recommend its use.

CSS Specifications

According to the CSS2 specifications, 'border' can be set to a combination of 'width', 'style', and 'color'. The value '0' sets the width, while 'none' sets the style. Both result in no border being displayed on the element.
