CSS Grid

CSS Flexbox Recap

Let's quickly recap CSS Flexbox and how it laid the groundwork for CSS Grid.

Introducing CSS Grid

Welcome to CSS Grid! It's a powerful layout system that gives you more control over the positioning of elements on a web page.

What is CSS Grid?

CSS Grid is a two-dimensional layout system that allows you to create complex layouts by dividing the page into rows and columns.

The Grid Container

The display: grid; property turns an element into a grid container. Within this container, you can define grid tracks and cells.

The Grid Tracks

Grid tracks define the rows and columns of your grid. You can specify their size, spacing, and alignment using the grid-template-columns and grid-template-rows properties.

The Grid Cells

Grid cells are the individual boxes created by the intersection of grid tracks. You can place content inside cells using the grid-column-start, grid-column-end, grid-row-start, and grid-row-end properties.

Grid Lines and Gutters

Grid lines are the visual boundaries between grid cells. Gutters are the spaces between grid lines. You can control the appearance and spacing of both using the grid-gap property.

Grid Template Areas

Grid template areas allow you to define named areas within your grid. This makes it easier to position and style content within complex layouts.

Grid Placement

Grid placement properties allow you to control how content is positioned within grid cells. These include justify-self, align-self, and place-self.

Grid Auto-placement

Grid auto-placement automatically places items into the grid based on the available space. You can control this behavior using the grid-auto-flow property.

Advanced Grid Features

CSS Grid offers additional features such as subgrids, named lines, and custom properties. These features provide even more flexibility and control over your layouts.

Nesting Grids

You can create grids within grids, allowing you to build complex, multi-level layouts. This is useful for creating headers, sidebars, and other nested structures.

Implicit Grids

In some cases, you don't have to explicitly define a grid. CSS Grid automatically creates an implicit grid based on the number of direct child elements within a container.

Grid Units

CSS Grid supports various units for defining grid tracks, such as px, em, %, and fr (fractional units). This flexibility allows you to create responsive layouts that adapt to different screen sizes.

Using CSS Grid in Practice

CSS Grid is a powerful tool for creating complex and flexible layouts. It can be used to build a wide range of web designs, from simple landing pages to complex dashboards.

Common Use Cases

Some common use cases for CSS Grid include:

  • Creating multi-column layouts
  • Positioning elements with precision
  • Building complex headers and footers
  • Creating responsive layouts
