On 12th of this month, ‘NEM official’ announced about the launch of its blockchain engine’s version 2.0 on Twitter. Audience’s excitement can be well estimated by the two hundred and sixteen likes and eighty-seven re-tweets of the post. What is unique about this blockchain engine is that it...
Netlify Functions for Sending Emails
23.4.2019
Let's say you're rocking a JAMstack-style site (no server-side languages in use), but you want to do something rather dynamic like send an email. Not a problem! That's the whole point of JAMstack. It's not just static hosting. It's that plus doing anything else you wanna do through JavaScript...
Tabs: It’s Complicated™
19.4.2019
I've said before one quick and powerful thing you can learn as a front-end developer just getting starting with JavaScript is changing classes.
const button = document.querySelector(".my-button");
const element = document.querySelector(".content");
button.addEventListener("click", function()...
Make it hard to screw up driven development
2.4.2019
Development is complicated. Our job is an ongoing battle between getting the job done and doing that job in a safe, long-lasting way.
Developers say things like, "I'm just going to do this quick and dirty first," because it's taken as fact that if you code anything quickly, it not only will...
WSJ Claim of $9 Mln Laundered Via Shapeshift Based on Flawed Investigation, Analysts Say
21.3.2019
Analysts have accused the Wall Street Journal of using flawed investigative methods and grossly overestimating the extent of alleged laundering via crypto exchange ShapeShift
Blurred Borders in CSS
20.3.2019
Say we want to target an element and just visually blur the border of it. There is no simple, single built-in web platform feature we can reach for. But we can get it done with a little CSS trickery.
Here's what we're after:
The desired result.
Let's see how we can code this effect, how we...
Designing An Aspect Ratio Unit For CSS
13.3.2019
Rachel Andrew says that the CSS Working Group designed an aspect ration unit at a recent meeting. The idea is to find an elegant solution to those times when we want the height of an element to be calculated in response to the width of the element, or vice versa.
Say, for example, we have a grid...
Smooth Scrolling for Screencasts
13.3.2019
Let's say you wanted to scroll a web page from top to bottom programmatically. For example, you're recording a screencast and want a nice full-page scroll. You probably can't scroll it yourself because it'll be all uneven and jerky. Native JavaScript can do smooth scrolling. Here's a tiny snippet...
CSS Algorithms
6.3.2019
I wouldn't say the term "CSS algorithm" has widespread usage yet, but I think Lara Schenck might be onto something. She defines it as:
a well-defined declaration or set of declarations that produces a specific styling output
So a CSS algorithm isn't really a component where there is some parent...
CSS Triangles, Multiple Ways
5.3.2019
I like Adam Laki's Quick Tip: CSS Triangles because it covers that ubiquitous fact about front-end techniques: there are always many ways to do the same thing. In this case, drawing a triangle can be done:
with border and a collapsed element
with clip-path: polygon()
with transform: rotate()...
Should I Use Source Maps in Production?
1.3.2019
It's a valid question. A "source map" is a special file that connects a minified/uglified version of an asset (CSS or JavaScript) to the original authored version. Say you've got a filed called _header.scss that gets imported into global.scss which is compiled to global.css. That final CSS file...
Using CSS Grid the right way
22.2.2019
Violet Peña has shared her recommendations for using CSS Grid. They basically boil down to these high-level points:
Use names instead of numbers for setting up our grid columns.
fr should be our flexible unit of choice.
We don’t really need a grid system anymore.
Although this is all great advice...
How @supports Works
18.2.2019
CSS has a neat feature that allows us to test if the browser supports a particular property or property:value combination before applying a block of styles — like how a @media query matches when, say, the width of the browser window is narrower than some specified size and then the CSS within...
instant.page
18.2.2019
instant.page is a pretty cool project from Alexandre Dieulot. Alexandre has been at this idea for half a decade now, as InstantClick is his and is essentially the same exact idea.
The idea is that there is a significant delay between hovering over a link and clicking that link. Say it takes...
Where Do You Learn HTML & CSS in 2019?
7.2.2019
The topic of how accessible it is for newbies and seasoned developers alike to learn CSS has been gaining steam as the complexity of the tools around it has become skewed more toward traditional programming. Rachel Andrew has much more to say about this in her post, HTML, CSS and our vanishing...
Netlify Makes Deployments a Cinch
22.1.2019
(This is a sponsored post.)
Let's say you were going to design the easiest way to deploy a static site you can possibly imagine. If I was tasked with that, I'd say, well, it would deploy whenever I push to my master branch, and I'd tell it what command to run to build my site. Or maybe it has...
The Great Divide
21.1.2019
Let’s say there is a divide happening in front-end development. I feel it, but it's not just in my bones. Based on an awful lot of written developer sentiment, interviews Dave Rupert and I have done on ShopTalk, and in-person discussion, it’s, as they say... a thing.
The divide is between people...
New CodePen Feature: Prefill Embeds
21.1.2019
I've very excited to have this feature released for CodePen. It's very progressive enhancement friendly in the sense that you can take any <pre> block of HTML, CSS, and JavaScript (or any combination of them) and enhance it into an embed, meaning you can see the rendered output. It also...
Using React Portals to Render Children Outside the DOM Hierarchy
15.1.2019
Say we need to render a child element into a React application. Easy right? That child is mounted to the nearest DOM element and rendered inside of it as a result.
render() {
return (
<div>
// Child to render inside of the div
</div>
);
}
But! What if we want...
Git Checkout at Previous Timeframe
9.1.2019
In the past I’ve blogged about checking out branches created on a specific date as well as sorting git branches by date, but one frequent usage of git and dates is checking out a commit at a given time in the past. For example, I often say “Weird, this feature was working a month...
