HTML video and audio lazy loading is now a web standard and quickly gaining support in all major browsers. Given Squarespace’s role in proposing and implementing it, we’re very excited to see how developers use it on the web. Let’s cover some best practices for using video and audio lazy loading in any website, as well as some gotchas to…

At Squarespace, many of our core products are built on web standards, and our engineers are constantly pushing the boundaries of the web’s capabilities. Occasionally, those boundaries reveal a limitation: an opportunity for the web’s native capabilities to grow. This post is the story of how we found such an opportunity to work with the standards community to improve the…

In the fast-paced world of software development, documentation often gets a bad rap. It's perceived as a chore, a necessary evil, and sometimes, unfortunately, an afterthought. But what if writing documentation could be as dynamic and collaborative as writing the code itself? What if it could be simpler to write and more practical to use?

Our teams love relational databases and the benefits ACID properties bring to us as engineers, but they have their limits, especially in horizontal scaling. We had to adopt new database tech across a fleet of highly available services while eliminating as much risk as possible… but how? Enter: change data capture patterning.

On the Unfold team at Squarespace, our mobile releases don't require much in the way of manual intervention or human oversight. In fact, we don’t have to give releases much thought at all. But, this was not always true. This post is a look into what these non-eventful mobile releases are like, dig into how much more eventful they used…

The outro recaps what you did – write technical documentation! – and introduces next steps like organizing a collection of documentation, revising existing content, and expanding your technical writing skills by joining the technical writing community.

After completing Parts 1, 2, and 3 of this tutorial, your once blank page now has technical writing – you're officially in the home stretch! Technical writing on a page becomes technical documentation only after you test, edit, and publish the content. Do not underestimate the exponential payoff that comes from testing and revising content. More than one technical writer…

In my opinion, creating good headings and organizing them in a way that’s helpful to readers is much more challenging than drafting content. So pat yourself on the back for completing Part 2 of this series and making it to Part 3. 👏 👏 👏 However, there are three things that undo exceptional headings and structure in technical documentation: content…

Part 1 of this tutorial introduced you to the content types that are most common in technical documentation. You also evaluated a real-life example as a reader, and you may have realized how headings are essential to a good reader experience. It’s because readers on the web do not read – they scan ¹ . People actually read 25% slower…

In the same way the term “books” includes fiction, nonfiction, and biographies as genres, the term “technical documentation” includes many different content types. But what sets technical documentation apart from books are reader traits. These traits are a result of what the reader does as they read technical documentation – they use the app.

Writing is a learned skill. No one person is a good or bad writer. 🙂 When a colleague asked me to mentor them on technical writing, I searched for a single technical writing article, guide, book, or tutorial that addressed three key things. Since I couldn’t find one, I decided to create a tutorial on technical writing.

Imagine you are editing your Squarespace website on your desktop browser and you want to add great photos that make your site stand out. At that moment, you realize those great photos are actually on your phone. Wouldn’t it be great if you could cut out all the intermediate steps and directly access your phone’s photo library right from the…

More so than any other level of the management chain, front-line engineering managers are the most attuned to the day to day realities of shipping software. Giving them a collective voice to surface what works and what doesn’t is critical to understanding the efficacy of organizational policy and process.

How do you make a website look good when you can't know how that website will look? It turns out this is one of the fundamental questions we work with at Squarespace. Since one of our goals is to make it easy for our users to create beautiful websites, we need to walk a delicate balance between constraints and freedom.…

Squarespace's site builder allows our millions of customers to build their unique sites. The content within a given site, like text and buttons, live within small sections called blocks. Earlier this year, the Core Layout team addressed the largest shortcoming of the block editing experience: the block editors didn’t match the modern Squarespace product design language that other features have…

As our suite of products has grown from a website builder and commerce tools to encompass much more, synchronizing frontend state across these products has become increasingly important. Complicating the matter, some products run in iframes, whereas others run in the main browser window. We’ve developed a scalable approach to synchronization that abstracts away these differences, which we call Universal…
