In 2007, Steve Jobs launched the primary iPhone, which revolutionized the world. However due to that, many companies handled the issue of adjusting the structure of internet sites from desktop to cellular by delivering fully completely different mobile-compatible web sites underneath the subdomain of ‘m’ (e.g., https://m.fb.com). And we had been all attempting to determine the best way to work on this new world of contending with cellular and desktop display sizes.
However after a couple of years, in 2010, Ethan Marcotte launched the idea of Responsive Design. Responsive Net Design is the concept that design and improvement ought to reply to the person’s conduct and setting based mostly on the display measurement, system, and orientation. And central to that concept was the provision of CSS Media Question, which allowed setting varied structure guidelines relying on the scale of the viewport.
The responsive design opened up many extra structure options with the assistance of Media Question. Frameworks like Bootstrap rose in recognition as a consequence of offering responsive grid methods. As per W3Techs, Bootstrap is utilized by 19.3% of all web sites, with a market share of 79.5%.
These days, element libraries (ReactJS) have gained recognition due to its ‘construct as soon as, deploy anyplace’ nature. A element is constructed as soon as and can be utilized anyplace within the structure to make complicated interfaces extra environment friendly. And people elements come collectively to create a webpage.
At present, you’ll be able to solely change the webpage structure with respect to the viewport utilizing Media Question. However when writing media queries for UI components, we’re looking for a “magic” viewport worth for a breakpoint like 320px – 480px for cellular gadgets, 481px – 768px for tablets/iPads, 769px – 1024px for small laptops and 1025px – 1200px for large display laptops/computer, in order that the goal ingredient has minimal dimensions, and the structure doesn’t break. This worth often differs from the viewport dimension and results in bugs when the inside container’s dimension or structure modifications.
This is among the points that CSS Container Queries try to repair. CSS Container Queries lengthen present media question performance with queries that rely upon the goal ingredient dimensions. And on this weblog, we are going to dive deep into the idea of CSS Container Queries.
Getting Began with CSS Container Queries
An important factor to learn about CSS Container Queries is that “containers” are the weather being queried, however guidelines inside the CSS Container Queries have an effect on solely the descendants of the container. In different phrases, chances are you’ll outline the ‘physique’ ingredient, ‘ foremost’ ingredient, or maybe occasion checklist objects. Then, CSS Container Queries will permit defining guidelines for the way components inside these change throughout container sizes.
CSS Container Queries are usually not as easy as common media queries. You’ll have so as to add the container property to the guardian UI ingredient to make CSS Container Queries work, however there’s a purpose, and we’ll cowl that subsequent.
Browser Assist
CSS Container Queries are by default enabled in Chrome (the most recent model). For easy and higher efficiency, you’ll be able to set up the most recent browser.
Be aware: In case you are not utilizing the above-recommended browser, the next CodePens may not work. So a picture showcasing the meant working instance might be supplied alongside the CodePens demo.
Comprise Property
CSS include property has been added to most fashionable browsers and has a good 90% browser assist when writing this text.
The include property is especially used for efficiency optimization by hinting to the browser which elements of the web page will be handled as unbiased and received’t have an effect on the opposite components of the web page. If a change happens in a single ingredient, the browser will re-render solely that half as an alternative of the entire web page. With include property values, we are able to specify which varieties of containment we need to use – structure, measurement, paint, Content material, or none.
The stage 3 draft specification provides the inline-size and block-size key phrases to include. As well as, the draft specification proposes some new properties:
Defines a component as a question container. Descendants can question facets of its sizing, structure, and state.
Specifies an inventory of question container names for @container guidelines to filter which question containers are focused.
A shorthand property to set each container-type and container-name.
Container-Sort
It assigns a question container to a component. Relying on the worth, descendants can question facets of its measurement, structure, fashion, and state of the item. This helps to make setting the include property simpler with arguments that mix completely different properties.
The container kind property can have the next values:
- Measurement: Creates a question container that helps dimensional queries on each the inline and block axis.
- Inline-size: Creates a question container that helps dimensional queries on the inline axis.
- Block-size: Creates a question container that helps dimensional queries on the block axis.
- Model: Permits for fashion queries by defining a question container.
- State: Permits for state queries by defining a question container.
Measurement, Inline-size, and Block-size are additionally given structure, measurement, and elegance containment.
However what does the CSS Comprise property used for optimization must do with CSS Container Queries? For CSS Container Queries to work, the browser should know if a change happens within the ingredient’s youngsters structure. It ought to re-render solely that element. The browser will know to use the code within the container question to the matching element when the element is rendered or the dimension of the container modifications.
Let’s take a look at include property with a small code instance.

As we are able to see within the above code block, we aren’t including the ‘container’ property to a extra distant guardian like ‘wrapper’ and retaining the container as near the affected ingredient as potential.
That’s the reason we should always appropriately sign the browser in regards to the change. Wrapping a distant guardian ingredient with a ‘container’ property will be counter-productive and negatively have an effect on web page efficiency. In worst-case situations of misusing the ‘container’ property, the structure could break, and the browser received’t render it appropriately.
That’s all for now in regards to the ‘container’ property. Now let’s have a look at the CSS Container Queries and the way they work.
Take a look at CSS Container Queries on 50+ completely different viewports. Strive LambdaTest Now!
What are CSS Container Queries?
A Container (additionally known as a Wrapper) is a component that comprises one other ingredient(s). So in easy phrases, CSS Container queries specify modifications to a component in relation to its guardian container or ingredient somewhat than the complete viewport.
(Desktop – 1084px)
(Cellular – 386px)
When a element is positioned inside an merchandise, it’s contained inside it. Which means we are able to question the width of its guardian and modify the element based mostly on that. CSS Container Queries allow builders to strategy responsiveness from a element standpoint, the place components on a web page are designed to be responsive as particular person models. Which means no matter the place these components are positioned on the web page, they may modify based mostly on the guardian ingredient’s measurement somewhat than the complete web page’s measurement.
After the container property has been added to the cardboard ingredient wrapper within the above code instance, we are able to write a container question. We’ve added a container property to a component with a container class, so now we are able to embrace any of its little one components in a container question.
.container {
container-type: inline-size;
}
Similar to a daily media question, we have to outline a question utilizing min-width or max-width properties and nest all selectors contained in the block. Nonetheless, we’ll use the @container key phrase as an alternative of @media to outline a container question.
@container (min-width: 500px) {
.card {
grid-template-columns: 1fr 2fr;
grid-template-rows: auto 1fr;
align-items: begin;
column-gap: 20px;
}
.card h2 {
padding: 0;
margin: 0.5em 0 0 0;
}
.card header {
grid-row: 1;
grid-column: 2;
}
.card .picture {
grid-row: 1 / 3;
grid-column: 1;
}
.card .Content material {
grid-column: 2;
grid-row: 2;
padding: 0 20px 20px 0;
}
}

CSS Container Queries present a brand new and refreshing strategy to responsiveness. Nonetheless, it’s in no way a substitute for media queries. As a substitute, think about it a cool new addition to the developer’s responsive toolbox.
What issues do CSS Container Queries clear up?
CSS Container Queries supply a novel answer for builders engaged on large-scale initiatives the place completely different elements make up completely different elements of the webpage. They permit elements to switch their look to suit the context through which they’re put. Which means the elements can be utilized repeatedly, making them reusable.
Many web sites have elements that want to alter their structure based mostly on the container’s obtainable width. This may increasingly not all the time be associated to the viewport’s measurement however to the place the element is positioned within the structure. CSS Container Queries present an answer for builders to alter element fashion and structure relying on the obtainable width of the container or guardian ingredient.
Right here’s a correct instance in order that we are able to see the facility of container queries:

See the Pen Container-Question demo by Aman Mandal (@aman-mandal) on CodePen.
Be aware: View this instance in Chrome Canary with container queries enabled.
For individuals who aren’t utilizing Chrome canary, listed here are the output photographs at completely different container sizes.
We created a easy card that resizes and adapts to suit any structure and container in our instance. Our one container has a width of ⅔ and the opposite considered one of ⅓. This implies our card element could have a width of 1066px and 534px at a viewport width of 1600px.
We would like our container to look barely completely different at completely different breakpoints relying on its obtainable house whereas remaining responsive. We may do that with a media question, however to do this, we’d must make modifications relating to the viewports meta-information somewhat than the container itself. This implies we should continuously look ahead to modifications to the display measurement and modify our elements in response to that specific measurement.
Though this may not appear to be a problem, it may rapidly result in using too many media queries to focus on if we had a number of containers as a result of we would wish to verify all components on the web page, not simply the cardboard element, are responsive.
That is the place CSS Container Queries come into play. Let’s go over our above code instance once more and see how we are able to flip this right into a container:
We would like our container to look barely completely different at completely different breakpoints relying on its obtainable house whereas remaining responsive. We may do that with a media question, however to do this, we’d must make modifications relating to the viewports meta-information somewhat than the container itself. This implies we should continuously look ahead to modifications to the display measurement and modify our elements in response to that specific measurement.
<div class="wrapper"> <div class="left"> <article class="card"> <!-- Card Content material --> </article>
To question components, we first must make the guardian ingredient a container by setting the container property on the guardian ingredient. The container property takes two values: container-type and container-name.
Discover how the ingredient with the .card class is wrapped by a guardian ingredient? This is able to be our guardian container, and our card would modify its measurement, structure, and types based mostly on the meta data of this ingredient.
Let’s go forward and make our ingredient with the left class a container, so its youngsters components will be queried based mostly on its meta-information.
.left{
container: inline-size;
}
We set the container property to inline-size as a result of we would like containment to occur on the inline axis.
The container property and worth are set on our .left class, which robotically turns the container ingredient right into a queryable container. So now, we are able to change the cardboard ingredient every time the scale of our container ingredient modifications.
We are able to change the fashion or structure of our card ingredient at sure breakpoints. We are able to set these breakpoints equally to how media queries breakpoints are set. You possibly can be taught extra about it by going by our weblog on CSS breakpoints.
Let’s have a look at the breakpoints we put within the above instance to see how CSS Container Queries deal with modifications based mostly on our breakpoints and the way CSS Container Queries evaluate to media queries.
In our instance, we began by constructing out how our card element would look when its guardian container has the smallest width, which is any width lower than 500px. We would like it to appear like this:
This is able to be our start line for our card element. Since its guardian container is now a container that may be queried, we are able to go forward and begin making modifications to the structure and elegance at completely different breakpoints relying on the present width of the guardian container.
We do this by setting breakpoints. Our breakpoint is when our guardian container is at a min-width of 500px (500px or better), and we begin defining a brand new search for our card container. Right here we would like our container to appear like this:
Code Instance:
@container (min-width: 500px) {
.card {
grid-template-columns: 1fr 2fr;
grid-template-rows: auto 1fr;
align-items: begin;
column-gap: 20px;
}
.card h2 {
padding: 0;
margin: .5em 0 0 0;
}
.card header {
grid-row: 1;
grid-column: 2;
}
.card .picture {
grid-row: 1 / 3;
grid-column: 1;
}
.card .Content material {
grid-column: 2;
grid-row: 2;
padding: 0 20px 20px 0;
}
}
If we would like our card ingredient to look barely completely different at one other breakpoint, we are able to merely observe the identical course of for each new breakpoint.
CSS Container Queries allow us to create extra strong and reusable UI elements that may adapt to just about any structure and container, as proven within the above two examples. This is able to’ve been much more troublesome with media question as a result of it depends on the data of the complete viewport.
With container queries, the cardboard element may very well be positioned in a slim or broad column on the webpage and nonetheless look good and responsive. Moreover, if there’s sufficient house in our container queries instance, it shows as a two-column structure, in any other case, it has a block structure.
In our instance above, container queries helped us obtain this:-
A block structure for smaller sections of the webpage:
A two-column structure for when we now have more room:
The examples above present the facility of CSS Container Queries and the way very important they’re within the component-driven improvement world. Now that we now have a fundamental understanding of CSS Container Queries and the way they operate, let’s have a look at a extra detailed code instance.

We created two comparable card elements that may resize and adapt to slot in any container through the use of the CSS Container Queries. Now, we would like our container to look barely completely different at completely different breakpoints relying on its obtainable house whereas remaining responsive. In order we are able to see within the above CSS code, we added 4 completely different breakpoints for 4 completely different layouts. Let’s take a look at them:
-
- For containers greater than 850px:
-
- For containers lower than 850px :
-
- For containers lower than 650px:
-
- For containers lower than 460px:
-
- For containers lower than 300px:
As we’ve seen from the earlier examples, CSS Container Queries are finest used for extremely reusable elements with a structure that is dependent upon the obtainable container house and that can be utilized in varied contexts and added to completely different containers on the web page.
It’s a Wrap!
As soon as the spec has been applied and broadly supported by browsers, CSS Container Queries may turn into a game-changing function. CSS Container Queries are an impending strategy for transferring past media queries tied to the viewport. For a few years, builders have desired the flexibility to alter a component’s width based mostly on its container’s width. Due to this fact, it is just logical that components have a option to be responsive based mostly on their guardian’s container meta data somewhat than the complete viewport.
Because it stands, CSS Container Queries are nonetheless in an early experimental section, and the implementation is inclined to alter. We hope to see the ultimate draft specs for this function quickly so we are able to all begin utilizing it. Till then, hold experimenting !!
Thanks for studying.
