Apr 05, 2025 pm 03:54 PMFAQs and solutions for CSS Flex layout responsive design
To build a responsive website, CSS Flex layout is a powerful tool. But sometimes, Flex layouts perform inconsistently at different screen sizes, which is usually related to viewport settings. For example, you want the pictures and text to be displayed side by side on a widescreen device; while on a phone screen, the pictures are located above the text. However, even with media queries, the layout may not be adaptable.
The root cause of the problem is the lack or incorrect viewport meta tags. The default viewport width of the browser is usually large (for example, 980px), causing media queries to fail.
Solution:
In HTML Partially add viewport meta tags to correctly set the viewport:
<meta name="viewport" content="width=device-width, initial-scale=1.0">
This line of code tells the browser to set the page width to the device width, with the initial scaling ratio of 1.0, so that the page can be rendered according to the actual width of the device before media query can take effect.
Complete code example:
The following code demonstrates how to switch between picture and text layouts through Flex layout under different screen sizes:
<meta name="viewport" content="width=device-width, initial-scale=1.0">Flexbox responsive layout picturetext
By adding viewport meta tags and adjusting the CSS code, you can achieve the desired effect by ensuring that .text
element is adaptable to the width under the small screen. Remember that correctly setting the viewport is the cornerstone of responsive design, which ensures that your media queries correctly respond to changes in different screen sizes.
