Indentation in design: a systematic approach

We didn t have a systematic approach to the solution. If there were noticeable discrepancies with the layout in the layout, then the problem was fixed locally.

The designer made a bug report, the frontend ruled according to the checklist: here the text stuck to the illustration, but here they did not follow the label, which ran to another input. Often the designer would sit next to the front-end, and together they would adjust the padding of each block at each screen resolution.

Due to the fact that we did not have a coherent system, the same errors appeared in every new project.

Designers arranged educational programs about the importance of vertical rhythm, the rules of internal and external, the rules for placing basic elements on the page. Frontenders gave lectures about BEM, talked about leading on the web, and organized courses on “layout for designers”. But each of the departments talked about their own world, not the general one.

It became clear that we needed an equally understandable tool for both designers and front-end developers.

If you disassemble the layout or page of the site by elements and look at the vertical spacing between them, patterns emerge. There are not so many vertical indents of different heights on a single site. For example, on the main Yandex there are only 4. On the Apple product page – 8.

In the next project, we tried to visualize the vertical indents. We created a separate page in the guide, wrote about vertical indents and showed how they are applied.

Frontenders have tried and approved this approach. This is how the vertical padding system was born. This is how our layouts look now from the inside:

After the first project, neither the designers nor the front-end developers realized how much the use of the vertical padding system would make the layout easier. But for several projects, we tested the system and made sure that it works. The system is especially useful on large sites, where we are talking about a bunch of information pages, each of which must be built according to a template.

How the system works

All page elements are grouped into blocks. The blocks are lined up according to the rules that the designer came up with.

We have conditionally divided the vertical indents into levels. The first level is the lowest indentation. For example, it is placed between the heading h4 and the paragraph or illustration and caption. The second level indentation beats off two such blocks. Etc.

Blocks that are different in meaning but of the same type now always include the same indents. The interrelationships between the blocks have become clear: the front-end looks at the layout and immediately sees the patterns that the designer thought. As a result, designers draw layouts more accurately, and it is easier for front-end developers to grasp the designers ideas.

How designers work with the system

We are working in Sketch. Symbols are suitable for vertical indents. We have a library that already has a standard set of vertical indents.

When a designer understands what spacing he needs, he takes symbols from the library and adjusts them to their heights and colors. Then it vertically indents the page and groups everything into a Vertical Rythm folder. For convenience, we have a small plugin that hides and shows the indented folder by hotkey.

Of course, padding the page is not a quick matter. It s dreary. But the profits are not acidic either. Layouts look neater; easier to draw after a break; the new designer, who is connected to the project, draws in the same coordinate system, there will be no surprise for front-end developers; project support is based on specific figures during development.

Plus, it s much easier to create responsive websites. The indentation changes the height for each breakpoint. Each of them has predictable behavior. You can draw one page layout, place indents, and not draw the rest of the layouts – thanks to the guide, the frontend will understand how the distances change without the layout.


How front-end developers work with this system

A word to our front-end team leader Kolya Shabalin:

“In the guide, the designer collects a table that contains all the breakpoints of all the indents of the project. This table is a single point for the entire project. All experts know where to look. Conveniently.

There is an agreement with designers that in layouts they share all indents with color. Let s say the green rectangle between the title and the text is 72px, and the red one is 80px.

Our system allows us to know nothing about numbers. From now on we operate with flowers. Why flowers? Because you want to make up, not suffer. What color the rectangle is, I will see on the layout, and I will refer to this color.

Each color is a row in the table, or, more simply, one set of indents. Another color is a different set of padding.


I wrote a mixin that can digest all these states. The mixin contains an array of states of all indents. It looks exactly the same as the table in the guide. Now we need to go to the mixin and tell him what color I see on the layout.

For example:

@include margin-level (bottom, green); – this is the indentation below the “green” color. How many pixels it doesn t matter to me anymore, the mixin will substitute everything for me. “


Our front-end developers estimate that the time to work with indents is reduced by 90%. Frontender spends 5-10 minutes setting up settings in SASS and no longer worries about indentation. He does not need to measure anything with rulers – he sees with his own eyes what indentation the block has.

If you see a first level indent, you apply a first level indent.


There are also negative aspects. By making life easier for the frontend, the system places an additional burden on the designer – indenting, grouping, and guides take time. In order not to stretch the timeline, we place rhythms not on all pages, but on unique blocks. The rest are formed according to the pattern.

The benefits and harms of the system

Vertical padding works best on large projects with lots of layouts, responsive layouts, and a multi-person team. It helps make layouts neat and predictable layout.

The effect is noticeable with large volumes of work. If you have a small project or one-page landing page, the system will most likely not work – firstly, it is difficult to maintain, and secondly, it takes more time.
