CSS Container Queries

In conventional responsive design, we depend on media queries to switch kinds in line with the total viewport length. This works neatly for adjusting layouts for various display screen sizes, but it surely falls brief when you want parts to evolve in line with their container’s length.

To resolve this example, Container Queries have been presented in CSS. They permit you to practice kinds to parts in line with the scale in their containing block, supplying you with extra granular keep an eye on over responsive design.

Let’s say now we have a Card part, containing an symbol, name, and a couple of paragraphs. The Card has two format modes: horizontal for massive monitors and vertical for smaller monitors.

Within the horizontal mode, the picture will likely be at the left, and the name and paragraphs are at the proper.

Within the vertical mode, the picture is on most sensible, and the name and paragraphs are underneath it.

We wish this Card to modify between those two modes. Historically, we might wrap the kinds across the @media question, as an example:

.card {
    show: flex;
    hole: 4rem;
}
.card .featured-img {
    width: 40%;  
}
.card .content material {
    width: 60%;  
}

@media display screen and (width <= 720px) {
    .card {
      flex-direction: column;
    }
    
    .card .featured-img {
      width: 100%;  
    }
  
    .card .content material {
      width: 100%;  
    }
}

The issue here's that Media Queries most effective account for the viewport length, no longer the container length. If the Card is positioned within a container with a width of 500px, the Card will nonetheless be within the horizontal mode, even supposing it is not appropriate for the container length. We would possibly finally end up with the content material and the picture being squished, or the picture overflowing the container.

That is one instance the place Container Queries may also be helpful. With Container Queries, we will practice kinds in line with the container's length, as an alternative of simply the viewport length.

To make use of them, we can wish to wrap our .card with a brand new container. On this instance, we can identify it .card-container. Then we will upload it with the container-type: inline-size declaration.

.card-container {
    container-type: inline-size;
    width: 100%;
}

The inline-size worth in particular permits querying the inline size, generally the width in horizontal writing modes of a container.

After we set container-type: inline-size on a component, we are necessarily telling the browser to regard that component as a container whose width may also be queried the usage of Container Queries. That is required for making use of kinds in line with the dimensions of the container, slightly than the viewport. The width may be vital to verify the container takes up the overall width of its guardian.

Now, we will practice the kinds in line with the container's length along with the Media Queries:

@container (max-width: 720px) {
    .card {
        flex-direction: column;
    }
    
    .card .featured-img {
        width: 100%;  
    }
    
    .card .content material {
        width: 100%;  
    }
}

The 2 playing cards from our instance must now transfer to the vertical format when the container's width is not up to 720px, irrespective of the present viewport length.
