If you have a limited-width container, say a centered column of text, “breaking out” of that to make a full-width element involves trickery. Perhaps the best trick is the one with left relative positioning and a negative left viewport-based margin. While it has its caveats (e.g. requiring hidden overflow on the body, the container needs …

Mike Solomon worked on a fancy scrollytelling post for Esquire and blogged about it. It has GIFs of each step along the way of figuring out not just position: sticky; but also using negative margins, wrapper divs, backgrounds, and even a smidge of JavaScript measuring to get it all right. What it doesn’t have is …

For the last six years, Vue, Angular, and React have run the world of front-end component frameworks. Google and Facebook have their own sponsored frameworks, but they might leave a bitter taste for anyone who advocates for an open and unbiased web. Vue is another popular framework that has multiple sponsors but isn’t run by …

Here’s a great in-depth post from Adam Silver about his journey to create an autocomplete field that’s as accessible as possible. There are so many edge cases to consider! There are old browsers and their peculiar quirks, there are accessibility best practices for screen readers, and not to mention dealing with the component design when …

Whenever a browser upgrades versions, it’s a little marketing event, and rightly so. Looks like for Firefox it’s about once a month, Chrome is ~6 weeks, and Safari is once a year. Chrome 80 just dropped, as they say, and we get a video and blog post. What strikes me about releases like this these …

I’ve been guilty of publicly bemoaning the complexity of HTTPS. In the past, I’ve purchased SSL certificates from third-party vendors and had trouble installing them. I’ve had certificates expire and had to scramble to fix them. I’ve had to poke and prod hosting companies to help me ensure things were going to renew correctly, and …

Interesting research from Aaron Peters on <img loading=”lazy” … >: On my 13 inch macbook, with Dock positioned on the left, the viewport height in Chrome is 786 pixels so images with loading=”lazy” that are more than 4x the viewport down the page are eagerly fetched by Chrome on page load. In my opinion, that is waaaaay …

Louis Lazaris, reacting to the idea of CSS4: The reason “CSS3” worked is because it was real. It was the successor to “CSS2.1”. Everything after CSS2.1 was considered to be under the umbrella of “CSS3”. The gist is that CSS4 isn’t real, so won’t work, and we don’t need it anyway. Perhaps I overestimate the …

Please raise your hand if you’ve ever faced never-ending content revision requests from your clients. It’s not that the changes themselves are difficult, but wouldn’t it be less complicated if clients could just make the revisions themselves? That would save everyone valuable time, and  allow you to turn your attention to more important tasks. In …

Short answer: Longer answer (same conclusion, just an explanation on why we might need this): Say you have an element that you style with a special data-attribute: You want to target that element and do special things when highlighting. That data-type attribute is part of a template, so it can have any value you set. …

Tab Atkins in 2012: There has never been a CSS4. There will never be a CSS4. CSS4 is not a thing that exists.

Just this morning, Chris shared a streamlined way to get a static site up and running with Netlify. As it happens, Sarah and I also wrote up a little something that expands that idea where a static site can pull content from WordPress using the REST API. Using Vue, Nuxt, axios, and Netlify, it’s possible …

PHP templating often gets a bad rap for facilitating subpar code — but that doesn’t have to be the case. Let’s look at how PHP projects can enforce a basic Model, View, Controller (MVC) structure without depending on a purpose-built templating engine.

There’s some famous quote that goes something like… When we’re young, we make simple things because that’s all we know. Then we learn how to make complex things so we make complex things. When we grow old, we learn to make simple things again. Brad recently wrote about this abstractly in regard to musicianship, but …

“Static Site Generator,” that is. We’ll get to that in a second. Netlify is a sponsor of this site (thank you very much), and I see Zach Leatherman has gone to work over there now. Very cool. Zach is the creator of Eleventy, an SSG for Node. One thing of the many notable things about …

Every time I start a new project, I organize the code I’m looking at into three types, or categories if you like. And I think these types can be applied to any codebase, any language, any technology or open source project. Whether I’m writing HTML or CSS or building a React component, thinking about these …

There’s been news about Chrome freezing their User-Agent string (and all other major browsers are on board). That means they’ll still have a User-Agent (UA) string (that comes across in headers and is available in JavaScript as navigator.userAgent. By freezing it, it will be less useful over time in detecting the browser/platform/version, although the quoted …

Have you ever needed a countdown timer on a project? For something like that, it might be natural to reach for a plugin, but it’s actually a lot more straightforward to make one than you might think and only requires the trifecta of HTML, CSS and JavaScript. Let’s make one together!

We just linked up the idea that offset-path can be cleverly used to set type on a path. Don’t miss Michelle Barker’s experimentation either, with drawing paths or animating text along a path. Dan Wilson has also been following this tech for quite a while and points out why the sudden surge of interest in …

A new podcast from Sean Fioritto inspired by Joel Califa’s term “Full Stack Anxiety”. … the little voice in your head says … “I should know all of this. Do I even know what I’m doing?” Why do web developers the world over feel like this? There is an episode with Joel talking about it …

Every so often, the fruits of innovation bear fruit in the form of improvements to the foundational layers of the web. In 2015, HTTP/2 became a published standard in an effort to update an aging protocol. This was was both necessary and overdue, as HTTP/1 rendered web performance as an arcane sort of discipline in …

Short story: Philip Walton has a clever idea for using service workers to cache the top and bottom of HTML files, reducing a lot of network weight. Longer thoughts: When you’re building a really simple website, you can get away with literally writing raw HTML. It doesn’t take long to need a bit more abstraction …

If you’re interested in leveling up your knowledge and skill of web performance, you can’t do better than learning directly from Scott Jehl.

Say you have a two-column layout: a main column with content. Say it has a lot of content, with sections that requires scrolling. And let’s toss in a sidebar column that is largely empty, such that you can safely put a position: sticky; table of contents over there for all that content in the main …

Catalin Rosu: Sometimes you need to type a long reply that consists of many paragraphs and wrapping that text within a tiny textarea box makes it hard to understand and to follow as you type. There were many times when I had to write that text within Notepad++ for example and then just paste the …

MVVM pattern MVVM (Model-View-ViewModel) je patern koji razdvaja aplikaciju na više komponenti tako da svaka komponenta ima svoje specifične odgovornosti. Pri korišćenju MVVM paterna “kod” aplikacije je razdvojen na tri dela: View, ViewModel i Model, ova arhitektura je preporučena od strane Google-a kao jedan od najboljih načina strukture koda Android aplikacija. Osnovne karakteristike ovog pristupa …

Šta je ViewPager? ViewPager je Layout Manager koji omogućava korisniku da se kreće kroz stranice podataka pokretima na levo ili desno, dok se pri promeni stranica izvršava i ugradjena animacija. Najčešće su te strane sa podacima su fragmenti, mada mogu da budu i nešto drugo kao npr. slike koje se slajduju… ViewPager se popunjava podacima …

Uvod Adapter je most između izvora podataka (Array objekat, List objekat…) i korisničkog interfejsa. Uloga adapter objekta (implementira Adapter interfejs) je da čita podatke iz različitih izvora podataka, i na osnovu njih popunjava View objekte članove nekog ViewGroup-a. Do sada smo koristili ListView ali preporuka je da se umesto listView-a koristi RecyclerView, a naručito kada …

Uvod U osnovnoj verziji adaptera se koristi samo jedan String podatak koji se smešta u neki od predefinisanih android layouta sa jednim TextView-om. Custom adapter se razlikuje od “običnog” po tome što je kod njega jedan element liste predstavljen sa više podataka te je potrebno definisati “složeniji layout” koji bi prihvatio i prikazao te podatke. …
