The ever-evolving landscape of web design is a thrilling space to be in with new CSS trends constantly emerging.
If you’re an early adopter like me you’re probably buzzing with excitement about things like CSS Grid Layouts CSS Blend Modes or even the typographic flexibility that allows for easy drop caps with CSS.
These new CSS advancements open up a world of creative possibilities for website design.
But traditionally we’ve had to wait to implement these exciting features due to the ever-present problem of browser support.
Who wants to build a site for a client that most browsers can’t even handle? It’s a frustrating reality for designers who are eager to push the boundaries of what’s possible.
Thankfully all hope is not lost! CSS Feature Queries offer a fantastic solution for bridging this gap and ensuring a positive user experience across the board even when dealing with browser limitations.
Understanding Browser Inconsistency: Graceful Degradation and Progressive Enhancement
Before we dive headfirst into CSS Feature Queries let’s revisit some common approaches for tackling browser inconsistency.
These two methods have been around for quite a while and represent different schools of design thought.
Graceful Degradation: Backwards Compatible Design
Think of Graceful Degradation as a “less is more” approach to design.
It focuses on providing all the bells and whistles in modern browsers but gracefully degrades to a lower level of functionality in older browsers.
It’s tempting to go all out with every shiny new CSS attribute but it’s crucial to remember that content is king.
Your visitors are there for the information and to interact with your website.
While the experience might be less fancy in older browsers it’s vital to ensure basic functionality remains intact.
They should still be able to view the content without encountering broken or missing elements.
Progressive Enhancement: Building Upon a Solid Foundation
Progressive Enhancement flips the script and takes a “build it up” approach.
It starts with a simple user experience that is consistent across all browsers guaranteeing the core content is accessible and usable.
Then the fun part begins! Advanced functionality is added on top only available to browsers that can handle it.
A helpful way to think about it: Graceful Degradation starts complex and aims for simplicity when needed while Progressive Enhancement starts simple and builds upon it for a richer experience.
Modernizer: A JavaScript Solution for Feature Detection
Modernizer is a JavaScript library that has become the go-to tool for implementing Progressive Enhancement.
It checks whether a browser supports cutting-edge web technologies essentially acting as a feature detector.
It analyzes the browser’s capabilities and returns either true or false allowing developers to test for specific technologies and provide fallback solutions for unsupported browsers.
This is where polyfills come in handy providing compatibility with older browsers.
While a valuable solution Modernizer does have its limitations.
It relies on JavaScript which though relatively small in size is still slower than using pure CSS.
And while it’s not a common occurrence what happens if JavaScript fails to execute? This defeats the purpose entirely making CSS Feature Queries a compelling alternative.
CSS Feature Queries: Native Feature Detection with CSS
CSS Feature Queries are a browser-native way to perform feature detection using CSS itself.
They allow you to determine if a browser has properly implemented a particular CSS property.

Essentially the browser reports back whether or not it supports a specific CSS property or value.
The result then dictates whether a block of CSS should be applied or not.
When working with CSS Feature Queries it’s helpful to maintain either a Graceful Degradation or Progressive Enhancement mindset.
With Graceful Degradation designers can provide fallback styles for features that aren’t supported.
The stylesheet will utilize the new features when available but gracefully degrade to a simpler presentation when not.
Browser Support for CSS Feature Queries
Overall browser support for CSS Feature Queries is quite good.
However it’s important to note that they are not yet supported in all browsers particularly older versions of Internet Explorer.
For the most up-to-date information check out Can I Use. Don’t let the lack of IE support discourage you! When planning your site consider what CSS elements will be unsupported and plan accordingly.
Putting CSS Feature Queries into Action
To truly understand how CSS Feature Queries work it’s best to experiment with some simple tests.
Write small snippets of CSS to check whether a specific feature is supported.
This hands-on approach will help you write and apply CSS based on what is (or isn’t) supported by a browser optimizing your page for the available features.
CSS Grid Layouts: A Case Study
Let’s take CSS Grid Layouts as an example.
They’ve been a hot topic in the web design world but their widespread adoption is still in progress.
Here’s where CSS Feature Queries can come to the rescue! We’ll use the @supports rule to target browsers with grid support.

You might notice that the syntax of a Feature Query (the @ symbol) is very similar to a Media Query making it easy to write and remember.
/* Styles for browsers that support grid layouts */ @supports (display: grid) { .grid-container { display: grid; grid-template-columns: repeat(3 1fr); gap: 1rem; } } /* Fallback styles for browsers that don't support grid layouts */ .grid-container { display: flex; flex-direction: column; width: 100%; }If the browser understands display: grid the styles within the @supports block will be applied.
If not the styles will be skipped and the fallback styles will be used instead.
In this example browsers that support grid layouts will display a grid with three columns and spacing between them.
Older browsers that don’t support grid layouts will display a fallback which could be a flexbox layout or even a simple block layout.

Drop Caps: Adding Elegance to Typography
Drop caps are a fantastic CSS feature that adds a touch of elegance to typography.
This property allows you to make the first letter in a paragraph larger similar to how drop caps are traditionally designed.
For instance the first letter of the first word in a paragraph could be the size of five lines of text styled in bold with a small margin on the right side.
However drop caps are not universally supported.
Therefore it’s important to create a fallback style that closely resembles what a supported browser would display.
In this example we’ll use the same color bold style and serif font for the fallback design.
/* Fallback for browsers that don't support initial-letter */ p:first-letter { font-size: 2em; font-weight: bold; font-family: 'Times New Roman' serif; float: left; margin-right: 0.5em; } /* Styles for browsers that support initial-letter */ @supports (initial-letter: 'A' 5em) { p:first-letter { font-size: 5em; font-weight: bold; font-family: 'Times New Roman' serif; float: left; margin-right: 0.5em; } }This approach ensures that even browsers without initial-letter support will display a decent rendition of the drop cap.
New Image Effects: Blending Modes for Creative Image Styling
The CSS world has exploded with new image effects and browser support as always varies.
Some of these new effects are simply stunning! Who would have thought overlays weren’t just a Photoshop thing anymore? Let’s delve into mix-blend-modes and explore how they can be applied to images when supported.
Beyond simply detecting whether a browser supports a specific feature Feature Queries can be used to bundle together a group of CSS declarations that will execute as a unit.
The following example might seem complex but it becomes clearer once we break it down.
<article class="image-overlay"> <img src="image.jpg" alt="Image Description"> </article>/* Styles for browsers that support mix-blend-mode and linear-gradient */ @supports ((mix-blend-mode: overlay) and (linear-gradient(to right #f00 #00f))) { .image-overlay img { mix-blend-mode: overlay; filter: brightness(1.1); position: relative; } .image-overlay::before { content: ''; position: absolute; top: 0; left: 0; width: 100%; height: 100%; background: linear-gradient(to right #f00 #00f); } } /* Fallback styles for browsers that don't support mix-blend-mode */ .image-overlay img { opacity: 0.7; }In this example we’re checking for browsers that support both the mix-blend-mode: overlay property and the ability to render a linear-gradient. If supported the image will be styled with a gradient overlay adding a vibrant red hue.
For browsers without mix-blend-mode support we use the not operator within the @supports rule.
This will apply some styles but they will be more limited compared to the styles applied within the query above.
