In Cascading Style Sheets, CSS grid layout or CSS grid creates complex responsive web design layouts more easily and consistently across browsers. There have been other methods for controlling web page layout methods, such as tables, the box model, and CSS flex box. The W3C Validation Service validates multiple versions of XHTML and HTML, outputting many useful errors and warnings to help users create a standards-compliant web page.
The CSS Grid Layout Module offers a grid-based layout system, with rows and columns, making it easier to design web pages without having to use floats and positioning.
The grid properties are supported in all modern browsers.
A grid layout consists of a parent element, with one or more child elements.
An HTML element becomes a grid container when its
display property is set to
All direct children of the grid container automatically become grid items.
The vertical lines of grid items are called columns.
The horizontal lines of grid items are called rows.
The spaces between each column/row are called gaps.
You can adjust the gap size by using one of the following properties:
grid-column-gap property sets the gap between the columns:
grid-row-gap property sets the gap between the rows:
grid-gap property is a shorthand property for the
grid-row-gap and the
grid-gap: 50px 100px;
grid-gap property can also be used to set both the row gap and the column gap in one value:
The lines between columns are called column lines.
The lines between rows are called row lines.
Refer to line numbers when placing a grid item in a grid container:
