I accept apparent some fizz about CSS Variables afresh and afresh had the befalling to use them as allotment of the front-end aggregation at Geckoboard. They apparent a actual specific botheration for us while actuality accessible to use, fast, and maintainable. In this post, I’ll call how and why we acclimated CSS Variables in aggregate with React to re-style our web app on the fly!

At Geckoboard, we body alive dashboards to affectation key metrics on TV screens. Actuality able to add your own personality to a dashboard is important to a lot of our customers, so a few months ago our architecture aggregation previewed a affection they were calling “Customization”.

The abstraction was simple: a anatomy area you abuse your dashboard with new accomplishments colors, accoutrement colors, font-sizes etc. and we would affectation a alive examination of what your dashboard will attending like.

As anon as the engineering aggregation saw the “live preview” aspect, we knew we had a hurdle to jump. Our armpit is a React appliance and administration UI updates is easy, about all our styles are accounting in SASS, so alteration the dashboard affair in such a acknowledging way would be a problem.

At this point we accurate two themes: aphotic and light. Since the absence affair was dark, we would override our capital CSS by loading a light.css stylesheet whenever a user chose the ablaze affair for their dashboard.

But now our architecture aggregation capital to abutment millions of accessible capacity and they bare to be activated after a folio reload, in a performant way… we had to amend what a “theme” was.

Here is an archetype of what a affair ability attending like in the new world…

Absolutely! This was a appetizing option, accumulation inline styles with React would beat best of the boxes. Our styles would be adjustable abundant to abutment any theme, a JSON affair would be accessible to anatomize and automated re-renders would be handled by React.

On a beginning codebase, we absolutely could accept taken this route. However, at the time of writing, we accept 29,951 curve of SASS in 566 files. Moving to inline styles would be one heck of change to make!

A few of us in the front-end aggregation had done some account about a new blueprint for built-in CSS Variables. It seemed absorbing so we absitively to body a affidavit of concept.

Note: There are some abundant frameworks about that handle styles in React. If this is an advantage for you again analysis out Radium, Styled Components ,and Styled JSX.

CSS Variables (Or CSS Custom Backdrop as they are clearly known) are a new affection of CSS that acquiesce you to ascertain placeholder ethics for CSS properties. The syntax of a capricious name is a cord starting with two dashes (e.g.–theme-primary-color), variables are again referenced application a new CSS action var(). Here’s what application a CSS Capricious looks like…

Now the accomplishments colour of my .header basic will be whatever amount I accredit to the capricious –theme-primary-color, in this case, ‘blue’. If at any time the capricious updates, the browser repaints automatically and the adapted appearance is applied.

In the aloft archetype the capricious is assigned on the document’s basis selector. Because this is the top akin element, the amount ‘blue’ will about be globally assigned to –theme-primary-color but variables can be redefined and additionally chase the cascade.

In this archetype the –theme-primary-color capricious is reassigned inside .sidebar so that aback it gets acclimated by .widget inside .sidebar it has the amount ‘red’. The aftereffect of this is that our attack will accept a dejected accomplishments and our aftereffect widgets will accept a red background.

In addition, if a capricious is referenced but is never defined, or if the browser you’re application doesn’t abutment CSS Variables, again it gets abandoned completely. So we can add a fallback for these cases absolutely easily…

This was a almost accessible move. In absolute there were 63 backdrop in our SASS that bare to change depending on the theme. To abstain accepting to manually add fallbacks in all these cases, we created a SASS mixin.

Then in our SASS we added the variables…

At this point we had a artefact that looked absolutely the same, because our CSS was consistently falling aback to the absence ethics we set, but we were accessible to alpha applying CSS Variables!

As I’ve mentioned, our UI is congenital in React, so we capital a way to administer the affair with React. Considering our capacity will be accessible as JavaScript objects, it is a absolute applicant to handle our 3rd assumption:

If we had a basic that took the affair as a prop and activated it as CSS Variables again React could booty affliction of re-renders for us aback the affair changed.

So far I’ve talked about defining variables in CSS, but variables can additionally be authentic with inline styles, either anon in HTML…

or by application the JavaScript setProperty api…

We congenital a React basic about the latter. It takes an article that maps capricious names to ethics (that aloof so happened to be what a “theme” looks like) and applies them as appearance backdrop on the document’s basis element. Actuality is a simplified adaptation of that component…

componentDidUpdate(prevProps) {if (this.props.variables !== prevProps.variables) { this.updateCSSVariables(this.props.variables);}}

As an accomplishing detail, we abundance our affair and handle updates with Redux, but here’s an archetype use after Redux…

Guess what – it formed like a charm! I was abashed how accessible it was to administer capacity like this. Aback the affair is adapted in accompaniment our basic anon applies the CSS Variables globally and the folio is re-rendered with the new theme. That was a acceptable feeling.

In this GIF there is a single, changeless CSS file, no styles are set inline and none of our React apparatus (except the affair applicator) charge to anguish about the theme.

Even admitting our styles are still in CSS, we now accept the abounding ability of JavaScript to account affair values. In the screenshot above, you may apprehension that the accoutrement accomplishments blush is automatically called based on the accomplishments color; this is not application transparency, we are artful an adapted blush best based on the accomplishments color.

Of course, we can’t allocution about new appearance of the CSS blueprint after browser abutment appearance its animal head. Unfortunately, at the time of writing, there is no IE abutment at all for CSS Custom Properties.
