I'm not deeply involved in web development, so I might not be using the right terms, but I have learned HTML, CSS, JavaScript, React, Next.js, and Struts. One recurring issue I face is getting my designs to be mobile-responsive. When I design mobile-first, they look terrible on desktop screens and vice versa. I've tried using Tailwind, but I often mess up the 'md:' classnames, resulting in poor layouts. For example, my personal portfolio, created with React and React Three Fiber, displays well on desktop but becomes a mess on mobile, causing me to prevent mobile users from accessing it until I can build a version for them. Is there any framework that can automatically detect when elements are too large for smaller screens and adjust them accordingly? If such a thing doesn't exist, how hard would it be to create something like that? I've been considering starting an open-source project that handles mobile responsiveness automatically, since dealing with media queries seems challenging. Are there existing solutions besides Tailwind or Bootstrap, and why is it so difficult to create such a tool?

Great question! The challenge with a tool that automatically resizes elements is subjective design intent. What looks good resized for one project might not work for another. Many developers find it easier to stick with manually adjusting designs based on content rather than relying on a tool. I’ve been using platforms like Gamma that handle responsiveness for presentations—maybe similar apps could offer some insight for your web projects!
To make your designs work better across different screen sizes, it's crucial to understand how layout functions in browsers. There are primarily three modes: flow, flex, and grid. The flow layout, which is the default, stacks elements on top of each other, making it perfect for narrow mobile screens. As you plan your layout, always start simply and add complexity within media queries. This will keep your CSS clean and manageable. It's also a good idea to keep your HTML organized semantically, so it flows naturally when read.
There are many component libraries and design systems that provide mobile responsiveness out of the box. While you still need to create your layouts with mobile consideration, libraries like Mantine help streamline the process by including built-in responsiveness features.
It sounds like your portfolio's design may not be accommodating for a range of screen sizes. If your design is only tailored to larger screens, it’s going to look off on mobile devices. Designing with flexibility for various screen sizes from the start is key; aim for mobile-first layouts that adapt as screens get larger.
Have you set up mobile-friendly breakpoints for your layouts? This is vital for ensuring that your content adapts as the viewport size changes. If you’re not adjusting your designs when the screen size increases, everything will look stuck in one layout.
