A list of amazing things that CSS can do!
EDIT: Some of these properties won't work in some browsers because of support. We can check for browser support using
@supports and add fallback styles accordingly. Please use Chrome to view the examples 🙂
This CSS property specifies how an element's fragments should be rendered when broken across multiple lines, columns, or pages.
We can retrieve values of the selected element in CSS by using
attr(). This method could be really helpful with accessibility purposes.
This CSS property sets whether the back face of an element is visible when turned towards the user. Thinking of a card flip UI?
Gradients are a wonderful thing. You might've used to style backgrounds with linear gradients but do you know we can use pure css to create pie charts with the help of
To better understand how
conic-gradients, reference the MDN docs on it
Who needs photoshop filter effects when you have CSS filters. 🙃
Filter functions applies graphical changes to the appearance of an input image. The effects we can achieve are as follows -
drop-shadow filter is pretty amazing. It lets you apply drop shadow to the input image.
This CSS property sets how an element's content should blend with the content of the element's background or its parent.
Amazing things can be achieved by mixing blend modes and filters with images and text. Learn more on MDN Docs.
One of my favourite things in books and magazines are the beautiful drop-caps. We can create drop with
This CSS property provides a way to customise wrapping adjacent inline content around complex objects rather than simple rectangular boxes.
Open the example in a different tab and try changing the width of the window and notice how the text wraps around the image.
This CSS property sets whether the lines of text are laid out horizontally or vertically. We can have these values-
horizontal-tb- Content flows horizontally from left to right, vertically from top to bottom.
vertical-lr- Content flows horizontally from left to right, vertically from top to bottom.
vertical-rl- Content flows horizontally from right to left, vertically from top to bottom.
Checkout this this example to see it in action.
10. Adding gradient to text
This is achieved with the combination of
-webkit-background-clip: text and
-webkit-text-fill-color: transparent CSS properties.
11. Smooth scroll snap
scroll-snap-type CSS property sets how snap points are applied on the scroll container.
This example shows vertical(
y) scroll with value
mandatory. MDN docs does a great job on explaining how to use other values such as
proximity and horizontal scroll(
These are just a few great things CSS can do. Possibilities are endless! 🥳

Be aware that rendering-heavy properties like
filterare not too good for performance when you have a lot of images out there.
Yes, coding is all about trade offs. So it all depends on use cases ☺
Agreed, definitely do not use too many advanced CSS attributes like this: codepen.io/ivorjetski/pen/dBYWWZ
That's awesome 😍😍😍
thanks for the tip!
you're abosolute right.!!
You have to admire the hidden power though. SVG filters are a science into themselves and can be used with this CSS property.
Anyway do you know of any benchmarks?
Don't have any data to show you, just words from experience and checking this stuff on private projects.
What I've found is that CSS filters performance drops are most visible when you're using them in animations. It can really screw up the UX. And when using it just for initial display - on high-end PC-s you might not even see the difference, but it's certainly noticeable on mobile devices.
I have some data and its really not that bad!
Thank you ever so much Una :D
Thanks! 🙂 For your question related to browser compatibility refer to this comment
Recently i tried mix-blend-mode but due to some strange reason, it did not work on one of my android phone chrome browser. Worked on others. So, the point is to make sure it works for you on supported platforms.
Yes, of course, we should always to check for browser support. But the good thing about CSS is that we can always add fallback styles in cases where our desired css properties are not supported. If a property is not supported CSS won't throw out errors, it will silently cascade to other styles so adding fallback styles works out of the box.
Completely agree. Thanks
BTW some feedback about this:
There is no need to be so harsh. You can give critical feedback without coming off this way. Also, the author did give the info in the article that some of these properties are not fully cross-browser yet, but that should not bar authors from talking about them.
Thanks Sara! 🙂
Sorry, did not mean to be harsh. If this is what you've read it as, I apologize. This just makes me upset a little, because browser diversity is important.
Yes, it's mentioned, but as I said: Don't get used to it (=creating for one browser).
And by stating - "Please use Chrome to view the examples", I am not advocating Chrome only websites but the reason was simple enough so that people can actually see the examples.
Okay, fine. Understood. And obviously, I agree with your polyfill/fallback part.
Anyway, I keep my point that sentences like these ("use XY for viewing this!") create a bad incentive/habit. Anyway, it gets off-topic, so let's agree to disagree. :)
I'm fairly certain that CSS content and by extension attr() is not read by most screen readers + browser combination, being part of presentation rather than real content. I'd reconsider the recommendation unless I'm wrong then find tell me to pipe down. 😁
From accessibility point of view I meant that when we add such content like tooltip on hover, what we can do is add the content in
aria-labelwhich will be read by the screen reader and then make use of the same
aria-labelthrough are CSS with
attr()for the normal flow. In that way we can have consistent content throughout.
Probably should've explained better 🙂
Hi Anya, thanks for the post, do you mean like this?
Case 1 reads "paragraph, hello a11y text, important info"
Case 2 reads "paragraph, hello a11y text" only but displays the same as case 1.
aren't the 'aria-label' tags outdated now?
No? aria-label attributes still very much a day to day support attribute. They are just not great to use unless you have to, your markup should describe your SR journey without needless overides. Do you have any specification to suggest they are out of date?
If what you're doing is purely decorative or there is accompanying text, etc., then no, it's not a, "You can't use it because it's inaccessible." There's certainly use cases for CSS content, for example, that are perfectly fine. It just depends on their use.
Not what I'm saying. And I quote "This method could be really helpful with accessibility purposes." This is not true.
In the codepen example the tooltip will never be explained to blind users, so in affect, sighted users will get the context but not the blind user. So I stand by what I said. CSS content should be used with care.
Great post Ananya! I wasn't aware of some of these properties, e.g.
backface-visibility. Looking forward to your next post. 🔥
Informative article! Thanks!
I especially like the
The conic gradient codepen doesn't seem to be doing anything (Firefox Nightly) -- I just see a white page. What am I missing?
Use Chrome. I'm on the latest mobile release and it works
No. "Use some other browser" isn't a solution. Especially when that other browser is Chrome.
Web standards exist for a reason -- if this only works in Chrome, it's nice to know what to avoid; however, your reply has led me to the answer I was looking for: having a look at MDN, Chrome and variants are the only browsers to support this, meaning it's not ready for web consumption.
CSS modal: codepen.io/Smakosh/pen/bYVVbL
Emoji validation: codepen.io/Smakosh/pen/owMzgw
These examples are really great! 🙂
Thank you! just shared your article with my co-workers!
I had never heard of
box-decoration-break, that's really cool!
FWIW, all of the examples work in Safari. Everything but conic gradient and scroll-snap work in Firefox also. The backface-visibility example will work everywhere if the
-webkit-prefixed version is added (for Safari) and the non-prefixed version to
Wow! Great article, thank you! Some are really really cool!
conic-gradientdoesn't work on Firefox (but I saw the result on Chrome).
Yes, I agree browser compatibility is an issue as with so many other features on the web but with CSS we can easily check support with
@supportsand add fallback styles accordingly. If a property is not supported CSS won't throw out errors, it will silently cascade to other styles so adding fallback styles works out of the box.
I'm viewing this content through the latest stable build of Firefox, and see a lot of broken image icons. Not sure degradation is working as expected.
With Google deliberately breaking ad blockers in future Chrome versions, there are likely going to be a lot more Firefox users sooner than later.
conic-gradientis awesome, I've been looking for it for a few months now. Thanks for the article!
It's a pity that it's only supported by Chrome yet, but the future is bright! 😌
The filters one had me yelling at my screen. Excellent list - definitely one I'll save.
Great article Ananya -- I had no idea of half or more of these CSS properties! It's great to see CSS taking over typical things that we had to do in Photoshop like drop shadow on an image and now even filters.
Thanks for sharing! 🎉
