CSS Media Query Not Applying Styles in Responsive Design Testing on Mobile Devices

Currently developing a responsive web application that needs to adapt seamlessly across various screen sizes... We've implemented media queries to adjust styles based on device width, but during testing, it seems styles intended for mobile devices are not being applied consistently. Here’s a snippet of the relevant CSS: ```css @media (max-width: 768px) { .header { background-color: blue; font-size: 1.5em; } } @media (min-width: 769px) { .header { background-color: green; font-size: 2em; } } ``` The expectation is that on devices with a width less than or equal to 768px, the header should turn blue and the font size should adjust. However, when testing on a Nexus 5X, it remains green with a larger font size. We’ve gone through multiple debugging steps: - Verified through Chrome Developer Tools that the media queries are in fact being triggered by resizing the viewport. - Ensured there are no conflicting styles that could be overriding the media query. This was done by using the `!important` flag temporarily, which confirmed the styles are not applied even when they take precedence. - Tried adding a viewport meta tag in the HTML: ```html <meta name="viewport" content="width=device-width, initial-scale=1.0"> ``` Despite these efforts, the problem persists, particularly on Android devices. Testing on iOS seems to work as expected, which adds to the confusion. Has anyone faced similar challenges with media queries in responsive designs while testing on various devices? Any insights or recommendations would be greatly appreciated. Thanks in advance!
