"CSS Container Query Converter Tool | Transform Media Queries to Container Queries"

CSS Container Query Converter Tool

Transform your media queries into modern container queries with this free tool. Container queries are more powerful because they respond to their parent's size, not just the viewport.

This tool supports converting:

  • Simple media queries: @media (max-width: 768px)
  • Compound queries: @media (min-width: 601px) and (max-width: 1024px)
  • Multiple nested selectors within media query blocks

Container query syntax: @container (max-width: 768px) { /* styles */ }

This is the element that will contain your components

How to use container queries:

  1. Define a containment context with container-type: inline-size;
  2. Query the container size with @container instead of @media
  3. Container queries respond to their parent's size, not the viewport

Frequently Asked Questions

Why use container queries instead of media queries?

Container queries allow components to respond to their parent container's size rather than the viewport size. This creates truly reusable components that adapt to wherever they're placed.

Are container queries supported in all browsers?

Container queries are supported in all modern browsers (Chrome, Firefox, Safari, Edge) from 2023 onwards. The polyfill option helps provide basic fallback styling for older browsers.

Can I convert all media queries to container queries?

Not all media queries should be converted. Media features like print, orientation, or color-scheme still work best as traditional media queries since they relate to the device, not component size.

CSS Container Query Converter Tool Guide

CSS Container Query Converter Tool:Reason I bulilt this So there I was, 2 AM, bleary-eyed, manually rewriting the same repetitive media queries into container queries for the fifth time that week. Coffee had stopped working hours ago. That's when I thought, "This is ridiculous. I'm building a tool for this." And here we are. What Does This Tool Actually Do? It takes your traditional media queries and transforms them into modern container queries. Why? Because container queries are truly powerful - they respond to the size of the parent element, not just the whole screen. It's a genuine game changer for component-based design. Look, I'm efficient in the best way possible. Writing the same conversion patterns over and over made me want to throw my laptop out the window. So I built this to do the repetitive work for me. Features That Work Exceptionally Well Basic query conversion - Takes your @media (max-width: 768px) ...

CSS Units: Stuff I wish Someone Had Told me

CSS Units: Stuff I Wish Someone Had Told Me May 19, 2025 • Running on: caffeine overload & regret Damn it. I just wasted another weekend fixing a website because I screwed up the CSS units. AGAIN. Can I confess something? I've been building websites for over 10 years, and I *still* get confused about when to use px vs rem vs em. It's embarrassing. Like, I should know this stuff by now, right? So last month I built this site for a law firm. Everything looked perfect... on MY screen. Then the client calls me all angry: "Your website's broken!" Turns out he had his browser font cranked way up, and my beautiful layout was a total mess - buttons overlapping text, things running off the screen, a complete disaster. Yeah, I know. Totally preventable. So I'm writing this down partly to get it straight in my own head, and partly in case you're making the same stupid mistakes I keep making....

Code Cleanup Tips I Wish Someone Had Taught Me Years Back

Code Cleanup Tips I Wish Someone Had Taught Me Years back Sigh. Just spent my entire Monday hunting down a CSS bug that I definitely caused myself. Turns out I was using the same class name on two different elements – classic sleep-deprived me from last month coming back to cause problems for current me. Look, I'm not here to preach about "code perfection" or whatever. But after 10+ years of building frontends and watching projects go from "beautiful new codebase" to "nightmare no one wants to touch," I've realized clean code isn't about impressing your peers. It's about not hating your life when you have to change something six months from now. So, let me share a few things I've picked up. These aren't theoretical concepts from a textbook – they're lessons learned through frustration, caffeine, and missed weekend plans. ...

Debugging Your Layout: How to identify and Fix Common CSS Grid Issues

CSS Grid makes me wanna pull my hair out sometimes! Last Tuesday I was building this photo gallery that looked PERFECT in my Figma design. Then I coded it up and... what a mess! Nothing aligned, things were overlapping, and I almost threw my MacBook out the window. Seriously though, if you've ever rage-quit your code editor because your grid layout is acting possessed, I feel you. So grab a coffee (or something stronger) and let's talk about the CSS Grid problems that have personally given me migraines and how I eventually fixed them. Why Do Our Grids Break? The Honest Truth So here's what I've figured out after staying up way too late debugging layouts for clients who needed stuff "yesterday": CSS Grid doesn't think like we do - My brain wants to see boxes, but Grid is thinking about lines and tracks Browsers are... well, browsers - Firefox does one thing, Safari does another, and Chrome is just being Chrome ...

Schema Markup Tool That Changed My Game: How I Finally Got Rich Results"

The Schema Tool That Changed Everything That's when I built the Schema Markup Generator tool. I wanted something super simple that would:   Let me pick exactly what type of content I'm creating (recipe, article, product, etc.)   Fill in fields using everyday language   Create perfect schema code without needing to understand the technical stuff The first time I used it on my banana bread recipe post, I was shocked. Within two weeks, my recipe started appearing with a gorgeous image, star rating, and cooking time right in the search results. The clicks to my site nearly doubled! How I Actually Use This Tool (The Real Story) So here's what I actually do now whenever I publish something new on my food blog: I grab a cup of coffee, open up the Schema Generator in a new tab, and pick "Recipe" from the dropdown. There's a bunch of options there - Article, Product, Video, Event, and more - but Recipe is my go-to since that's what my blog is all ab...

The SEO Benifits of proper JSON Formatting

The SEO Benefits of Proper JSON Formatting May 20, 2025 • 8 minute read So there I was last Tuesday, staring at my screen for hours trying to figure out why my client's website had suddenly vanished from Google. Literally gone. After tearing my hair out and downing way too much coffee, I finally spotted it - a broken JSON-LD snippet with a missing comma and an extra quote mark. Such a tiny error, but it had completely tanked their search visibility for almost three weeks. It hit me again just how insanely important proper JSON formatting is for SEO these days. Nobody really talks about it much, but man, get this wrong and you're basically invisible online. Why JSON Formatting Matters for SEO JSON has pretty much taken over as the standard language for data on the web. Google and other search engines are obsessed with structured data in JSON for...

Meta Tags That Improve SEO: Google looks for this in 2025

Meta Tags That Boost SEO: What Google Actually Looks For in 2025 Dude, last month I was pulling my hair out fixing a client site that disappeared from Google. They wasted $5,000 on this so-called "SEO expert" who crammed in every meta tag known to mankind - even the ancient ones Google hasn't cared about since like forever ago. So I stripped out all that junk and stuck to the stuff that actually works. Boom - traffic up 73% in six weeks! Figured I'd dump my notes here since there's so much garbage advice floating around. Look, I'm no SEO rockstar trying to sell you some course. Just a regular front-end dev who keeps getting called to fix SEO messes. This is all stuff I've tested on actual client sites - not theoretical BS from some Google algorithm whisperer. The Meta Tags That Actually Matter in 2025 Google's gotten crazy g...

How I Fixed Core Web Vitals and Traffic Jumped - Some Tips

Man, I just wrapped up three brutal weeks fixing Core Web Vitals for a client's online store. Their mobile scores? Total garbage - 23/100. The poor folks couldn't figure out why their traffic was in free fall. After I dug in and fixed their issues, scores jumped to 87. And what do you know? Traffic started climbing back up. Not a coincidence. Figured I'd dump my brain here because honestly, most of the articles out there make this stuff sound like rocket science. It's not. Let me break it down over a virtual coffee. What Core Web Vitals Actually Are (No BS Version) Google loves their fancy terms, but Core Web Vitals are just three things that measure if your site is annoying users: Largest Contentful Paint (LCP) - Your main content is crazy slow to appear. Nobody waits 5 seconds to see what they clicked on. ...

The CSS Grid Generator That Finally Made Sense to Me

OK so here's the deal - for the longest time, whenever a client asked me for anything beyond a simple layout, I'd start sweating. "Can we make the gallery look more like Pinterest?" they'd ask. Or "We want the sidebar here, but these three sections need to line up exactly." I'd smile and say "sure thing!" while inside I was thinking "oh crap, not again." I kept hearing that CSS Grid was supposed to fix all this, but have you ever actually tried to learn it from the docs? Fr units, minmax functions, auto-this and template-that... after 20 minutes my brain would turn to mush and I'd go back to my trusty old flexbox hacks. And that worked fine... until it didn't. The Day I Got Caught Bluffing So there I was, sitting with this potential client who runs a local art gallery. She's flipping through my portfolio, nodding along, when she points to a competitor's site with this gorgeous layout - images...

The 1.618 Magic: How I Accidentally Fixed Improper Layouts

The 1.618 Magic: How I Accidentally Fixed improper Layouts 3am. Red Bull #3. Client meeting in 6 hours. And this layout still looks... off. We've all been there, right? That moment when you've tried every font combo, color tweak, and alignment trick in your arsenal. The point where you're one click away from trashing everything and starting over. That was me, 2016. Third revision on a jewelry site homepage, client already hated the first two versions. I was THIS close to calling in sick for our morning meeting. Then my roommate (motion graphics guy) stumbled in from his late shift, looked over my shoulder and mumbled something like "proportions are off, try the phi thing." The what now? Oh yeah, that golden ratio stuff from art history. The 1:1.618 thing with the seashell spiral. Honestly, I only remembered it because I had it on a cheat ...
