Today I finally released the project I’ve been working on for the last two years at MIT CSAIL: An HTML-based language for creating (many kinds of) web applications without programming or a server backend. It’s named Mavo after my late mother (Maria Verou), and is Open Source of course (yes, getting paid to work on open […]
I’m a strong believer in lowering the barrier of what it takes to create rich, interactive experiences and improving the user experience of programming. I wrote an article over at Smashing Magazine aimed at JavaScript library developers that want their libraries to be usable via HTML (i.e. without writing any JavaScript). Sounds interesting? Read it […]
Today I needed a quick tool to compare the loading progression (not just loading time, but also incremental rendering) of two websites, one remote and one in my localhost. Just have them side by side and see how they load relative to each other. Maybe even record the result on video and study it afterwards. […]
Those of us who use promises heavily, have often wished there was a Promise.prototype.resolve() method, that would force an existing Promise to resolve. However, for architectural reasons (throw safety), there is no such thing and probably never will be. Therefore, a Promise can only resolve or reject by calling the respective methods in its constructor: var promise = […]
I adore Github Pages. I use them for everything I can, and try to avoid server-side code like the plague, exactly so that I can use them. The convenience of pushing to a repo and having the changes immediately reflected on the website with no commit hooks or any additional setup, is awesome. The free […]
Recently, when I was making the minisite for markapp.io, I realized a neat trick one can do with CSS variables, precisely due to their dynamic nature. Let’s say you want to use a property that has multiple versions: an unprefixed one and one or more prefixed ones. In this example we are going to use clip-path, which […]
I have often lamented how many JavaScript developers don’t realize that a large percentage of HTML & CSS authors are not comfortable writing JS, and struggle to use their libraries. To encourage libraries with HTML APIs, i.e. libraries that can be used without writing a line of JS, I made a website to list and promote them: markapp.io. […]
As part of my preparation for my talk at CSSDay HTML Special, I was perusing the most recent HTML specs (WHATWG Living Standard, W3C HTML 5.1) to see what undiscovered gems lay there. It turns out that HTML sliders have a lot of cool features specced that aren’t very well implemented: Ticks that snap via the […]
Women speaking up about the sexism they have experienced in tech is great for raising awareness about the issues. However, when no positive stories get out, the overall picture painted is bleak, which could scare even more women away. Lucky for me, I fell in love with programming a decade before I even heard there is a […]
Anyone who follows this blog, my twitter, or my work probably is aware that I’m not a huge fan of big libraries. I think wrapper objects are messy, and big libraries are overkill for smaller projects. On large projects, one uses frameworks like React or Angular anyway, not libraries. Anyone who writes Vanilla JS on a daily […]
