Welcome! I’m Roman, a front-end web developer at Datadog. I love CSS, and most of the things I do, write, or think about are CSS-related. On this site I collect my experiments and articles about it (and, occasionally, about some other topics).
Sometimes I find myself improving the ways I write CSS: I’m an author of Hayaku, bemto-components, bemto for Pug.js, and used to maintain Stylus.
Below you will find links to some of the articles I wrote and experiments I did, alongside some other stuff.
with tags: #Anchor Positioning #Future CSS #CSS Round #Experiment #CSS
There is one old, yet unsolved, CSS problem: shrinking containers to fit the content when it automatically wraps. While not intentional, anchor positioning allows us to come closer to solving it, at least for a few cases. In this article, I’ll demonstrate how we can use anchor positioning to neatly decorate wrapping text or elements in flex or grid contexts.
with tags: #Scroll Driven Animations #Future CSS #CSS Variables #Experiment #Practical #CSS
In my fourth article about scroll-driven animations, I explore how we can transfer the state of one element to a completely different place on a page by connecting them with a unique identifier in CSS via a timeline-scope.
with tags: #Blog
I did create a new work-in-progress blog where I would post random things. I wanted to create a more personal space for a while, and it would allow me to separate less polished posts from the elaborate articles on my main site.
with tags: #Scroll Driven Animations #Future CSS #CSS Variables #Experiment #Practical #CSS
After solving the fit-to-width text, stuck state for sticky elements, and scroll shadows, I wondered: how many other items from various CSS wishlists could I solve with scroll-driven animations? A lot. Styling flex and grid rows and columns, staggered animations, wrap detection, and more — all in my new article.
with tags: #Scroll Driven Animations #Future CSS #Experiment #Typography #Practical #CSS
What if I will tell you how we could solve fit-to-width text with pure CSS without any hardcoded parameters? Curiously, scroll-driven animations will allow us to do just that! Join me as I continue exploring the experimental implementations of the latest specs.
with tags: #CSS Variables #CSS Logic #Style Queries #Experiment #Practical #CSS
Over the past few years, I wanted to be able to select a value from a list in CSS by toggling a single custom property. We have the “space toggle” for booleans, and hopefully, one day, we’ll get style queries, but what about today? In this article, I present you with the technique I recently discovered.
with tags: #Scroll Driven Animations #Position Sticky #Future CSS #Experiment #CSS
Stuck state for sticky headers? “Proper” solution for scrolling shadows? Highlighting the currently shown sections in a Table of Contents? All these things could become possible with the new scroll-driven animations spec. Today, I gather and explain some of my experiments with this new CSS feature.
with tags: #Practical #Experiment #React #TypeScript
After 16+ years of experimenting with CSS & HTML, I am a bit tired. Time flies, and new technologies emerge. What would you say if, from now on, I will start doing my wild experiments with, let’s say, React and Typescript instead? In my new article, I’ll show you how easy it is to have conditional hooks in React — and more!
with tags: #Anchor Positioning #Future CSS #Experiment #CSS Variables #CSS
Anchor positioning might be one of the most exciting features coming to CSS. It is currently available under an experimental flag in Chrome Canary, and after playing with it for a bit, I couldn’t stop myself from sharing what I found. In this article, I will show you some of my experiments.
with tags: #Practical #CSS Variables #CSS
One of the things I love about CSS is how some of the properties hide a lot of depth inside. For that reason, visibility was always one of my favorites. In this article, I will talk about one of its interesting aspects and will propose an idea: what if we would never use visibility: visible?
with tags: #Practical #CSS Counters #Typography #CSS
A few years ago I wanted to share one little-known CSS feature — a built-in list-item counter for ordered lists. But then there were a few browser issues preventing us from using it fully. Now, given that most of those bugs are fixed, we can try starting using them for our lists.
with tags: #Practical #Blog #Performance #JS #Fonts
I was digging into some of the performance issues during my work for a few weeks, and I thought that it can be interesting to see how those could be applied to my site. I was already quite happy with how it performed (being just a small static site) but managed to find a few areas to improve.
with tags: #CSS Grids #Practical #CSS #Design
My site’s design came through a lot of iterations, including the latest complete rewrite and a partial redesign, but its layout is something I used for a while. In this article, I’ll describe what I tried to achieve with it and how it was re-implemented using CSS Grids.
with tags: #Practical #Blog #Meta #JS
For a new site update I have implemented a site-wide search, and in this article, I would write about the solution I have used for this, as well as would talk about what had to be done and what issues are left.
with tags: #CSS Grids #Practical #CSS
CSS Grids specification contains a lot of different things. And, for some of them, there exist multiple ways of how you can achieve them. In this article, I’ll write about one trick with grid-template-areas that could help you name your intersecting columns or rows.
with tags: #Blog #Meta #CSS #Design
A New version, new tools, new techniques, new everything — I had a lot of fun in rewriting and re-coding my site, and I think there could be some interesting stuff inside. In this post, you’ll find some words about it alongside a not-so-precise changelog.
with tags: #Experiment #CSS Variables #CSS #HTML
Is it possible to sort some data using only HTML and CSS? The answer is “Yes”, and in this article you would see one experimental way to achieve this with CSS variables and an order property. Even if it is not practical and bad for accessibility, it is still fun.
with tags: #Experiment #CSS Logic #CSS Counters #CSS
HTML&CSS-only gomoku game? Binary logic in CSS via counters? So many combinators, Edge stops to understand what is even going on? All of this and a bunch of other weird CSS stuff in the experiment that I started back in 2013.
with tags: #Practical #CSS Flex #Responsive #CSS
Flex display mode allows us to create a lot of interesting interactions. In this article I’ll show how to use it to implement a responsive block which could substitute one content with another, all based on which one would fit inside the container.
with tags: #Project #Practical #React #BEM
Working within a React stack and using Styled Components, I found out that I still miss a lot of aspects of BEM. This lead to me starting a new side-project which not only allows to use BEM-style elements and modifiers, but also enhances the overall developer experience.
with tags: #Practical #Accessibility #Bugs #CSS #HTML
After playing a lot with HTML & CSS, I present you with a very robust and practical solution to one of the most annoying problems: keyboard-only focus on interactive elements. All thanks to tabindex in HTML and almost to no CSS.
with tags: #Experiment #HTML #CSS
Sometimes there are very unusual mechanics hidden deep in the interactions of HTML and CSS. In this article I show one of those — the nuances of how HTML labels interact with inputs and CSS applied to them.
with tags: #CSS Specificity #Future CSS #CSS #Preprocessing
Specificity is one of the most unique and complex aspects of CSS. And right now, the only way to control it are to add stuff to it. But what if we could have a way to reduce the specificity? I’ll look into the coming-up features of : not () and how they could help us to achieve this.
with tags: #Practical #CSS Logic #CSS Variables #Future CSS #Preprocessing #Bugs #CSS
CSS variables are very powerful, and they allow to do a lot of interesting things. But there are no native conditionals that we could use in CSS with them. In this article I’ll talk about one of the ways we can fake such conditions with calculations.
