Differences Between CSS Media Query 'max-width' and 'width <='In the realm of CSS media queries, there are two common ways to specify

Recently, while working on a website design project, I had the following media query in my codebase:

@media only screen and (max-width: 480px)

but after introducing Stylelint, it modified the query to:

@media only screen and (width <= 480px)

During a code review, a collaborator raised questions about this change. To quickly validate the modification, I turned to ChatGPT for assistance. Surprisingly, it pointed out that using relational operators like "<=" is not valid CSS as CSS doesn't support such comparisons. This made me question the validity of the change introduced by Stylelint.

I'm curious to know more about the differences between the two queries and whether the updated version is indeed valid. Any insights or explanations would be greatly appreciated! Thank you. :)

Answer №1

CSS3 was hailed as the final iteration of CSS due to its modular nature, allowing for dynamic updates by WHATWG and W3C without affecting other modules. This approach differed from previous versions which were released as whole packages.

The introduction of Media Query by W3C in June 2012 did not initially include support for the range feature, leading to the creation of min-width and max-width. The addition of operators like <= came later on, with the release of Media Queries Level 4 Module in May 2017.

Despite being published in 2017, the official drafting process for Media Queries Level 4 Module was not completed until December 2021. Browser support plays a significant role in the adoption of new features, as users may take years to update their browsers.

While range is considered a newer feature with potentially limited browser support, it may no longer be a crucial factor given the evolution of web technologies over time.
