Background colors for the menus are also defined here.
Here we have a base size for navigation items as -nav-size that will set both the height and width of a closed navigation menu to 12vh(which is 12% of the viewport height).
Variables are a powerful feature introduced in CSS Level 3 that greatly simplifies the task of organizing CSS code. We have a spacer between a header and a section.First up is the :root block, which contains CSS variables that will be used throughout the rest of the file. I’m not a JavaScript developer, but I think they call it Props. It’s possible to create a spacer that accepts different variations and settings. Let’s tackle the above questions one by one. Should we style them based on their parent’s display type (Flex, Grid).vertical layouts? Eg: A spacer inside a stack Vs a spacer that adds a left space. How a spacer component will take its width or height inside a parent? How it will work in horizontal vs.Here are some questions that I thought about: Now that you got the idea of spacer components, let’s dig into some expected challenges when using them. This will eventually result in a creepy code. For a large design system, it’s not scalable to keep adding margins to components. And this is where margin creeps into component code: for spacing compositions of components. Its only purpose is to add a space between the left edge and the wrapper.īut in the real world, we do need spacing outside of components for composing them into pages and scenes. That’s a with an inline style width: 16px. I first noticed this while inspecting Facebook’s new design CSS. The spacing might be on X page, but not in Y. Margin can’t be used directly to the component, because it’s an already built design system.Let’s suppose that a section needs a 24px margin from the left, with those restrictions in mind: I was pointed to this article that discusses the concept of avoiding margins and to use spacer components instead of them. 61% of the voters prefer margin-bottom over margin-top.Īnd the JavaScript tool you’re using should wrap each item in its own element. Even more, CSS Tricks did a poll between margin-bottom and margin-top.
To avoid such an issue, it’s recommended to use a single-direction margin as per this article. In the mockup above, one element has margin-bottom and the other has margin-top. In that case, the greater margin will be used, and the other will be ignored. In simple words, margin collapse happens when two vertical elements have a margin, and one of them has a greater margin than the other.
For example, in the previous example, I added margin-bottom: 1rem to add vertical spacing between the two stacked elements.Īs margin can be added in four different directions (top, right, bottom, left), it’s important to shed light on some basic concepts before diving in with example and use cases. It’s used to add spacing between an element and another. Quite simple, isn’t it? However, this can get more and more complex when dealing with components that have a lot of details and child elements. I used padding for the inner spacing, and margin for the outer one. In CSS, it’s possible do the spacing as below: Let’s suppose that we have an element, the spacing within it is inner, and the spacing outside it is an outer spacing. For this article, I will call them outer and inner. Spacing in CSS has two types, one that is outside an element, and the other is inside it. CSS Math Functions: Min(), Max(), Clamp().In this article, I will cover everything you need to know about spacing in CSS, the different ways of achieving that, and when to use a padding or margin. Without spacing, it will be hard for a user to skim a page and know what items that are related and what are not. When grouping multiple design elements, the user can decide how they relate to each other by the amount of space between them. If two or more elements are close, then the user will assume that they somehow belong to each other.
