Change firefox colors
Ideally, webpages could detect when high contrast mode is enabled and then make themselves more accessible. All this is great, but it’s still not quite ideal. At the moment, Firefox deals with text on images by drawing a backplate on the text. What about text that is set on top of images? If the image isn’t a single color, some parts may have high contrast, but others may not.
Doing this all automatically and in a way that works for every application and website is hard.įor example, how should high contrast mode handle images? Photos taken in high or low light may lack contrast, and their subjects may be hard to distinguish. It can reduce the visual complexity of the screen, force high contrast colors between text and backgrounds, apply filters to the screen, and more. Depending on what operating system is being used, high contrast mode can make a wide variety of changes. High contrast mode increases the contrast of the screen so that users with low vision have an easier time getting around.
When these settings are enabled we say that a website visitor has high contrast mode enabled. To keep the web accessible, many browsers and OSes offer high-contrast settings to change how web pages and content looks. Though the WCAG (Web Content Accessibility Guidelines) set standards for contrast that authors should abide by, not all sites do. The lack of distinction between text and its background can cause them to “bleed” together. For visitors with low vision web pages with low or insufficient contrast can be hard to use. When we talk about the contrast of a page we’re assessing how the web author’s color choices impact readability. By the end, you’ll have a greater understanding of how media queries work in Firefox, and why the prefers-contrast query is important and exciting. Finally, we’ll walk through the media query implementation in Firefox. We’ll start by defining high contrast mode, then we’ll cover the importance of prefers-contrast. In this article, we’ll walk through the design and implementation of the prefers-contrast media query in Firefox.
