Unlock the Power of Grid Systems in Web Design
What are Grid Systems?
A grid system is a fundamental concept in web design that helps create a structured and consistent layout. It’s a collection of vertical and horizontal lines that define a framework for stacking design elements. Grid systems are project-agnostic, meaning they can be applied to any project, and consist of rows, columns, and gutters (the space between rows and columns).
Why Use Grid Systems?
Grid systems offer numerous benefits, including:
- Easy creation of responsive web designs and mobile-friendly layouts
- Predictable approach to scaffolding layout designs, improving productivity
- Simplified calculation of element widths and heights
Building a Custom Grid
In this article, we’ll explore how to build a custom grid using CSS. We’ll focus on using the float property, which is supported by all browsers. Our project will utilize HTML5 and SASS (SCSS) for its powerful features, such as nesting and the parent selector.
Project Setup
To get started, clone our starter repository and follow these steps:
- Install dependencies using npm or yarn
- Start the dev server
- Open a new terminal tab to watch and compile your SASS file
Designing the Grid
Our grid markup consists of six rows with varying numbers of columns. We’ll use a naming convention for our column classes, such as col-1-of-2, to target specific elements for styling.
Styling the Grid
We’ll use a combination of CSS rules and SASS variables to style our grid. This includes:
- Setting up a responsive unit (rem) for easy calculation
- Using the
calc()function for complex width calculations - Implementing the
:not()pseudo-selector andlast-childpseudo-class for selective styling - Creating vertical and horizontal gutters using margin and padding
Calculating Column Widths
We’ll use the calc() function to calculate the widths of our columns, taking into account the horizontal gutters. This involves subtracting the gutter width from the total row width and dividing the result by the number of columns.
Final Thoughts
Our custom grid system is now complete, covering various scenarios and allowing for easy customization. By understanding how grid systems work, you can create your own custom grid and take your web design skills to the next level.
