The Typed Object Model

20.11.2019
I help write technical documentation and one feature I've been writing about this year that has really stood out is the Typed Object Model (or Typed OM). If you haven't come across it yet you would be forgiven as it's pretty new. It falls under the CSS Houdini suite of API's and on the surface...

How We Perform Frontend Testing on StackPath’s Customer Portal

15.11.2019
Nice post from Thomas Ladd about how their front-end team does testing. The list feels like a nice place to be: TypeScript - A language, but you're essentially getting various testing for free (passing the right arguments and types of variables) Jest - Unit tests. JavaScript functions are doing...

Finally, it Will Be Easy to Change the Color of List Bullets

14.11.2019
In my germinating years, the general advice was this: <ul> <li><span>List item</span></li> <!-- ... --> </ul> li { color: red; } /* bullet */ li span (color: black; } /* text */ Not terrible, but not great. You're "resetting" everything...

A Super Weird CSS Bug That Affects Text Selection

12.11.2019
You know how you can style (to some degree) selected text with ::selection? Well, Jeff Starr uncovered a heck of a weird CSS bug. If you: Leave that selector empty Link it from an external stylesheet (rather than <style> block) Selecting text will have no style at all....

Query JSON documents in the Terminal with GROQ

7.11.2019
JSON documents are everywhere today, but they are rarely structured the way you want them to be. They often include too much data, have weirdly named fields, or place the data in unnecessary nested objects. Graph-Relational Object Queries (GROQ) is a query language (like SQL, but different) which...

Some Things You Oughta Know When Working with Viewport Units

6.11.2019
David Chanin has a quickie article summarizing a problem with setting an element's height to 100vh in mobile browsers and then also positioning something on the bottom of that. Summarized in this graphic: The trouble is that Chrome isn't taking the address bar (browser chrome) into account when...

Float Element in the Middle of a Paragraph

4.11.2019
Say you want to have an image (or any other element) visually float left into a paragraph of text. But like... in the middle of the paragraph, not right at the top. It's doable, but it's certainly in the realm of CSS trickery! One thing you can do is slap the image right in the middle of...

Comparing the Different Types of Native JavaScript Popups

31.10.2019
JavaScript has a variety of built-in popup APIs that display special UI for user interaction. Famously: alert("Hello, World!"); The UI for this varies from browser to browser, but generally you’ll see a little window pop up front and center in a very show-stopping way that contains the message...

Are There Random Numbers in CSS?

29.10.2019
CSS allows you to create dynamic layouts and interfaces on the web, but as a language, it is static: once a value is set, it cannot be changed. The idea of randomness is off the table. Generating random numbers at runtime is the territory of JavaScript, not so much CSS. Or is it? If we factor in...

The `hidden` Attribute is Visibly Weak

16.10.2019
There is an HTML attribute that does exactly what you think it should do: <div>I'm visible</div> <div hidden>I'm hidden</div> It even has great browser support. Is it useful? Uhm. Maybe. Not really. Adam Laki likes the semantics of it: If we use the hidden...

A Snippet to See all SVGs in a Sprite

8.10.2019
I think of an SVG sprite as this: <svg display="none"> <symbol id="icon-one"> ... <symbol> <symbol id="icon-two"> ... <symbol> <symbol id="icon-three"> ... <symbol> </svg> I was long a fan of that approach for icon systems...

Get Total Address Information with Geocode API (Sponsored)

4.10.2019
Getting address information is vitally important. Whether shipping a package, tailoring a user experience to location, or using that data to help localize language on a website, getting location information wrong can lose a sale or brake feature. Let’s take a look at an API I recently found...

Meeting GraphQL at a Cocktail Mixer

26.9.2019
GraphQL and REST are two specifications used when building APIs for websites to use. REST defines a series of unique identifiers (URLs) that applications use to request and send data. GraphQL defines a query language that allows client applications to specify precisely the data they need from...

Random Notes from a JAMstack Roundtable

23.9.2019
I hosted a JAMstack roundtable discussion at Web Unleashed this past weekend. Just a few random notes from that experience. I was surprised at first that there really is confusion that the "M" in Jamstack stands for "Markdown" (the language that compiles to HTML) rather than "Markup" (the "M"...

Some HTML is “Optional”

11.9.2019
There is a variety of HTML that you can just leave out of the source HTML and it's still valid markup. Doesn't this look weird? <p>Paragraph one. <p>Paragraph two. <p>Paragraph three. It does to me, but the closing </p> tags are optional. The browser will detect...
