Release of Vanilla framework v3.0

Bartek Szopka

on 10 January 2022

This article is more than 2 years old.

We’ve just released Vanilla v3.0 – a new major update to our CSS framework. It includes a few significant updates and improvements around spacing variables, responsive breakpoints, a new expanding search box and various updates to existing components. Important aspects of the release include dropping a noticeable chunk of deprecated styles and components and removing IE support.

In this blog post we will cover the most important changes introduced with Vanilla v3.0:

Refactoring of spacing variables

We’ve always put a lot of attention into making sure components in Vanilla are consistently spaced and that all text and block elements align properly to our baseline grid. To make it possible while keeping the framework flexible, we used to have quite a large number of spacing variables in our SCSS code. These were used to add various amounts of horizontal or vertical spacing to the elements.

We also had separate variables for “inner” and “outer” spacing. These turned out to be confusing, as it wasn’t always clear for more complex components if the given space should be considered “inner” or “outer”. The other aspect that made Vanilla spacing complicated was the density multiplication factor that could be changed on a framework level. It affected some of the spacing variables (that we called “scaleable”), but not the others. It was not widely used and was the source of some confusion and bugs.

For Vanilla 3.0 we decided to refactor the spacing variables and reduce the number of them. We did this by removing the separation of “inner” and “outer” spacing, merging different variables that share the same values and removing the density multiplier and all variables that it affected. We still kept separate variables for horizontal and vertical spacing (to make it clear which values should be used in given directions), but they all follow the same naming conventions. So, “small” horizontal spacing has the same value as “small” vertical one.

Alongside this work, we also cleaned up and refactored some spacing related mappings.

This allowed us to reduce the number of our main spacing variables from 20 to around 10 with much more clear and consistent naming.

You can learn more about spacing in Vanilla in our docs or check our migration guide about how to update spacing variables in your project for Vanilla v3.0.

Tidying up of responsive breakpoints

While working on updates for Vanilla v3.0, we noticed some inconsistencies in the way different parts of the framework were using media query breakpoints. It seemed that different components and utilities changed their responsive behaviour or style at different breakpoints, making it harder to understand how screen size affects the style or layout.

We did an extensive audit of all our components and utilities that used media queries. We then simplified the way Vanilla handles responsive changes and fixed any inconsistencies we found.

Overview of the scope of the responsive breakpoints audit in Vanilla

The biggest change was to remove the ‘medium’ breakpoint which was the main source of inconsistencies. Some components used it as their max-width value, others as min-width.

By dropping it we now have only 2 main breakpoints in Vanilla 3.0: $breakpoint-large and $breakpoint-small, and they divide the possible screen widths into 3 ranges:

  • small screens (smaller than $breakpoint-small)
  • medium screens (starting at $breakpoint-small and smaller than $breakpoint-large)
  • large screens (from $breakpoint-large and bigger)

Additionally, some components that require more granular responsiveness can still use $breakpoint-x-small (to target mobile screens in portrait mode) or $breakpoint-x-large (to target large widescreen displays).

You can learn more about media query breakpoints in Vanilla documentation or read about how to migrate breakpoints to Vanilla 3.0 in our guide.

Dropping IE support

One of our main priorities in Vanilla is to make sure our styles work across all browsers. With CSS features moving forward, keeping Vanilla compatible with Internet Explorer has required additional effort and code. With Microsoft moving their focus to their new Edge browser, the number of users still on Internet Explorer has been significantly dropping.

In 2021 across all our Canonical websites we had almost 50 million visits, of which less than 5500 have been visits from Internet Explorer, which is less than 0.01%.

This small number of Internet Explorer users of our sites led us to the decision to remove Internet Explorer from browsers supported by Vanilla starting with release v3.0. This allowed us to remove many of the custom styles and fallbacks that we had to maintain, most notably complete separate implementation of the grid (that used flexbox instead of the CSS grid).

Vanilla v3.0 doesn’t contain a lot of new features or components because we’ve been adding them regularly during the development of Vanilla v2 releases. One of the few new features introduced specifically in this version is the new expanding search box.

In Vanilla v3.0 we removed some old deprecated styles around the main navigation component, which allowed us to implement new features for it.

The expanding search box was first introduced on the website. With the effort of guest developers (thanks Min and Fran!) who joined the Vanilla squad, it was refactored to Vanilla standards and upstreamed as a part of the framework, now published in v3.0.

Summary of removed styles and components

One of the main reasons we started planning the v3.0 release of Vanilla was to remove a large number of deprecated styles and components. Introducing a major version update allows us to finally get rid of some legacy code. This means we can clean up the codebase and reduce the size of the Vanilla CSS file.

Almost 20 different features, variants and components have been removed from Vanilla in release v3.0. Most of them already had their new recommended equivalents implemented in v2.0.

Most notable would include:
