Introduction
Welcome to "CSS Grid Layout". In this book you will learn all about the CSS grid layout model and how to create complex and responsive grid-based designs. You will learn about all the properties of grid containers and grid elements.
By the end of this book, you will be able to use the grid layout to create responsive layouts and handle all kinds of scenarios.
Let’s get started.
key concepts
CSS3 Grid Layout is a powerful two-dimensional layout system that allows you to create complex grid-based layouts on web pages. It provides precise control over the placement and alignment of elements within a grid container. Here's an overview of CSS3 Grid Layout and its key concepts:
Grid Container
● To create a grid layout, you need to designate an element as the grid container by applying the display: grid property.
● The grid container can be either a block-level or inline-level element.
Grid Tracks and Grid Cells
● Grid tracks are the columns and rows that make up the grid layout.
● By default, tracks are created automatically based on the content and size of the grid items.
● You can also explicitly define tracks using properties like grid-template-columns and grid-template-rows.
Grid Items
● Grid items are the elements placed inside the grid container.
● They can occupy one or more grid cells, spanning across multiple rows and columns.
● Use the grid-column and grid-row properties to position and span grid items within the grid.
Grid Lines
● Grid lines are the horizontal and vertical lines that define the boundaries of the grid cells and tracks.
● They can be referred to using line numbers or names assigned to them.
Grid Areas
● Grid areas are rectangular areas formed by combining multiple grid cells.
● You can assign names to grid areas using the grid-template-areas property.
● By referencing these area names, you can easily position grid items within specific areas.
Grid Template
● The grid template is used to define the structure of the grid by specifying the size and arrangement of tracks.
● Use properties like grid-template-columns, grid-template-rows, and grid-template-areas to create the grid template.
Grid Gap
● Grid gap refers to the spacing between grid cells and tracks.
● Use properties like grid-column-gap and grid-row-gap to define the size of the gap.
● grid-gap is a shorthand property that sets both column and row gaps simultaneously.
Alignment and Justification
● CSS Grid provides various properties to control the alignment and justification of grid items.
● Use properties like justify-items, align-items, justify-content, and align-content to align items within the grid container.
● Additionally, justify-self and align-self properties can be used to override alignment for individual grid items.
