By systemizing the basics of typography and house, and leaning into the inherent fluidity of the online, a free new CSS instrument referred to as Utopia affords an alternative choice to breakpoint-driven design. This shared language between design and growth streamlines communication and encourages the creation of bespoke constraints on your tasks to make sure constant and harmonious designs.

Twenty years in the past, as we launched into our voyage from the snug, predictable shores of print design to the fluid and ever-changing open seas of the World Broad Internet, John Allsopp encouraged the acceptance of “the ebb and flow of things”. Ten years later, Ethan Marcotte coined the term “responsive web design”, kickstarting a seismic shift from fixed-width desktop websites — and their separate cell counterparts — to single codebases of versatile design.

However we didn’t embrace the ebb and circulation. Probably not. As an alternative, we settled on a system of arbitrary breakpoints, and there the expedition ended. Inflexible “magic numbers” tied to real-world gadgets plagued our CSS and directed our design processes. Builders right now are sometimes handed a group of mockups for cell (320px), massive cell (400px), pill (768px), small desktop (1024px), and huge desktop (1440px). The hassle expended in producing so many discrete artifacts is an inefficient use of time and assets. It additionally perpetuates the archaic observe of making device-specific web sites.

Moreover, with so many distinctive reference supplies in play, builders are sometimes left to guess on the logic — if any — used within the design course of. This will result in a seemingly infinite variety of comparable values getting into the codebase, needlessly growing the load of the CSS and the complexity of the venture’s upkeep. This convolution swells exponentially with the variety of device-specific mockups generated in addition to the variety of design contributors concerned.

The Promise Of Utopia

A method to make sure our designs really feel at house on extra gadgets is so as to add extra breakpoints, enabling extra nuanced design tweaks at extra display sizes. This comes with the price of a extra laborious design course of, extra mockup technology, extra code, and extra documentation.

One other means is to lean into the fluidity of the medium, recognizing this perceived limitation because the benefit it really is. As an alternative of tightening our grip by loading up on breakpoints, we are able to let go, relinquishing a few of that management and permitting the medium to share the load. We will embrace the ebb and circulation with a extra fluid and systematic method to our design foundations.

In conversations with shoppers and colleagues, we discovered ourselves struggling to articulate these considerably nebulous ideas. To deliver the thought into actuality we gave it a reputation: Utopia. A single phrase to confer with a specific mind-set concerning the fundamentals of fluid responsive internet design. Listed here are the advantages as we see them:

  • Design and develop quickly utilizing a handful of associated guidelines, constructing the system, not each permutation of its contents at arbitrary breakpoints.
  • Create bespoke constraints on your tasks to make sure constant and harmonious designs.
  • Streamline communication and collaboration between design and growth.
  • Visualise the invisible: componentize responsive house, codifying its implementation and habits.
  • Swap jarring breakpoint jumps for buttery-smooth interpolation, with programmatically tailor-made sort and house scales for each display dimension.

The Origins Of Utopia

Utopia emerged throughout years of labor on the coalface, designing and creating in company and product contexts. We noticed some frequent patterns and pitfalls, and have step by step zeroed in on an answer, iterating with actual shoppers.

We began with a easy spreadsheet-based calculator in 2018, however speaking the advantages of fluid responsive considering was difficult. A casual dash at Clearleft in early 2020 resulted in utopia.fyi, the place we revealed a few of our ideas alongside a fluid type scale calculator.

Fluid Kind Scales

Typesetting with modular scales isn’t a brand new idea. It’s a confirmed mathematical means to make sure harmonious relationships between sort sizes in a design. However the place conventional print-derived typographic programs are designed to work at particular web page sizes, Utopia can unlock elegant typography for all gadgets.

By defining a appropriate sort scale for a small display and one other for a big display, we are able to let the browser interpolate easily between the 2, based mostly on the present viewport dimension. This leads to a set of sort sizes that’s all the time in tune with itself, with out manually setting sizes for a number of breakpoints.

Considering by way of steps slightly than values, we permit the pc to calculate the optimum sizes, slightly than laboriously working them out ourselves. This declarative mind-set chimes with how CSS itself works: we inform the browser what we need to occur and the browser works out how to do this.

This additionally creates a shared, tailor-made language between designers and builders. As an alternative of referring to a heading dimension change from, say, “1.687rem to 2.3125rem”, this neat set of choices permits you to say: “Step 2 to Step 3”. By including the intentional friction of named steps and embracing this self-imposed constraint, we are able to guard in opposition to an infinite variety of magic quantity font sizes infiltrating our codebases and designs.

Utopia encourages the curation of a system sufficiently small to be held in short-term reminiscence, slightly than one so sprawling it have to be consistently referred to.

Designing With Fluid Typography

We’ll sometimes begin a venture by defining a appropriate physique copy font and dimension at nominated min and max viewport widths. The precise sizes depend upon a product’s fonts, visible model, content material, structure, and viewers. We do that by experimenting in Figma with chunks of reasonable copy from the shopper, in addition to any design course insights we’ve uncovered collectively. At this level, we’re most fascinated about legibility, line lengths, line heights, dimension, and weight distinction — all of the substances that mix to make an applicable studying expertise.

After this experimentation, we’ll have a good suggestion of the scales that can work for the venture and it’s time to go to the Utopia type scale calculator.

You’ll be able to specify scale steps, and the instrument will map tough font sizes to mathematical sort scales. (Large preview)

Right here we’ll map the tough font sizes to mathematical sort scales, pulling the values into Figma — manually, for now — to substantiate they’re appropriate for the content material.

You’ll be able to learn extra about designing with fluid type scales on the Utopia weblog.

Creating With Fluid Typography

To tug these design foundations into code, the developer visits the same URL because the designer. They will export CSS straight from the instrument and drop it right into a venture.

The instrument generates CSS for fluid sort scale with CSS Customized Properties, however you can too use CSS Clamp. (Large preview)

Utopia depends closely on CSS customized properties and CSS locks. This has two advantages: it’s completely opt-in, and the values are tweakable within the browser.

Aspect notice on conserving your values malleable: This can be a essential design determination within the Utopia calculator. We all know from expertise that each one values are topic to alter as a venture proceeds. Digital design is a fluid course of. Design instruments like Figma are unimaginable, however they will’t present you the way your fonts will render in each browser on each gadget. Content material typically adjustments throughout tasks. Usability testing can throw up unexpected points. Stakeholders emerge with their very own design preferences. Simply bear in mind the mantra: “A digital product is rarely completed” and permit the system to flex, change, and develop as you’re employed.

With the fluid sizes uncovered by customized properties, there are two principal methods to implement them. In any declaration, slightly than set a font-size worth as a static unit (e.g. px), we confer with the step dimension:

h2 {
  font-size: var(--step-2);

Alternatively, by making a small set of single-responsibility utilities, we are able to create fluid parts with a single class:

.u-step-2 {
  font-size: var(--step-2);
<h3 class="u-step-2">Heading</h3>

Fluid Area Palettes

Area is usually created ad-hoc by designers, and guessed at by builders. Utopia goals to unravel this by standardizing the foundational unit of house utilized in design and growth. This creates a shared understanding and a typical set of intentional, fluid gaps for use by each disciplines. The fluid space calculator is the newest instrument within the Utopia assortment.

Taking “Step 0” from the fluid type scale as our base unit, we deploy a set of multipliers to create a number of house models. To maintain issues easy, we confer with them as T-shirt sizes: (S)mall, (M)edium, (L)arge, and so on. Because of the fluid base unit, these values subtly shrink and develop in response to display dimension.

Just like font sizes, however for house: meet the fluid space calculator. (Large preview)

The place many programs swap space values at arbitrary breakpoints, Utopia has an alternate take. Every particular person house unit can interpolate to a unique unit between your min and max breakpoints. Out of the field, Utopia creates “single-step pairs” that take one step up the ladder of sizes (2XS → XS, XS → S, and so on) however the instrument additionally permits you to create any variety of customized pairs.

These pairs can create extremely steep slopes (XS → 3XL), excellent for dealing with spacing for hero slats, and even reverse slopes that get smaller because the viewport width expands (2XL → XS).

Creating programs with fluid areas: the pairs will be excellent for dealing with rising spacing and reverse slopes that get smaller because the viewport width expands. (Large preview)

Designing With Fluid Area

Inside Figma, we’ll create a set of house parts for min- and max-sized areas. Utilizing variants, we are able to simply swap between every T-shirt dimension. A Figma plugin that automates this course of is on our roadmap.

Utilizing these areas as guides, we are able to place them between our parts to make sure visible consistency. We’ve discovered that after a brief time frame, the handful of house values commit themselves to your reminiscence, and laying out conforming designs with out the house guides turns into second nature.

We’ve built a demo to point out how this comes collectively within the browser, and the way intentional house turns into with Utopia.

You’ll be able to learn extra about designing with a fluid space palette on the Utopia weblog.

Creating With Fluid Area

Very similar to the typographic tool, we are able to export CSS straight from the space calculator and implement it with customized properties or utility lessons, like so:

.grid-of-two {
  show: grid;
  grid-template-columns: repeat(2, 1fr);
  grid-gap: var(--space-s-l); // (S) 18px → (L) 44px
  margin-bottom: var(--space-xs); // 14px → 17px

With a shared palette of fluid areas, we’ve discovered we not want mockups of each aspect at a number of viewport widths. As a developer utilizing Utopia, you now tackle a few of the accountability for the nuance of the responsive design of your venture. This house system empowers you to color the suitable fluid house throughout your interface as you see match.

The place particular parts require bespoke designs on smaller screens, a focused mockup will be created. A web site header is an effective instance. This permits the designer to spend their time extra correctly, specializing in thorny design issues, slightly than creating mockups of conditions which might be robotically resolved by Utopia.

It’s no exaggeration to say that this method has revolutionized the best way we develop for the online, and has quickly elevated the velocity at which we are able to flip flat designs into harmonious, fluid, and intentional digital layouts. It’d really feel considerably unintuitive to design this fashion at first however as soon as it clicks, you received’t need to return.

Utopia In The Actual World

One of many key milestones within the growth of Utopia was throughout Clearleft’s engagement with the Pure Historical past Museum. We labored carefully with the digital staff to reimagine the Wildlife Photographer of the Year web site, the net illustration of the biggest competitors of its variety on the earth.

Within the bodily exhibition, the images are thoughtfully organized, the supporting info fantastically typeset and punctiliously positioned. We dedicated to the identical diploma of consideration for the digital model. Working with this assortment of awe-inspiring property, the job of the brand new web site was easy: “Make the {photograph} the star”.

This mindset permeated by means of the design foundations and lent itself completely to making use of our Utopian rules. If the purpose was to show the imagery and related content material in the absolute best means on each gadget, we had two choices. We might both saturate our code with mounted breakpoints, or settle for the ebb and circulation, lean into the fluid medium of the online, and permit the pc to suit the content material to its show.

Each picture has the house to breathe and really feel in tune with its environment on any gadget, on the National History Museum website. (Large preview)

The results of this venture was an immersive digital incarnation of the bodily expertise, with each picture given the house to breathe and really feel in tune with its environment on any gadget. You’ll be able to learn extra concerning the venture within the case study, and listen to about it on the Clearleft podcast.


With this method, each character and each house in each element on each web page is tied to a typographic step or house dimension. Though this method shortcuts sure design choices in the course of the venture, it’s not an alternative to good design — it takes a talented designer to arrange the suitable sort and house palettes and handle them because the design evolves.

Whether or not we’re making a design system or one thing smaller, the professionals of a scientific method nearly all the time outweigh the cons. Relying on the scale and scope of a venture, introducing a system can really feel like overengineering. The Utopia method is designed to be as light-weight as potential, appropriate to be used on tasks of all sizes and styles.
