CSS Grid Layout is a powerful layout system that allows developers to create responsive and structured web layouts efficiently. One of the critical components of CSS Grid Layout is grid-template-rows, which plays a significant role in defining the height and structure of rows in a grid. This article will explore grid-template-rows in depth, covering its syntax, values, browser compatibility, related properties, and practical examples.
I. Introduction
A. Overview of CSS Grid Layout
CSS Grid Layout provides a two-dimensional grid-based approach to web design. It allows items to be arranged in a grid format, controlled through properties that define the structure of the rows and columns. The layout can adapt to different screen sizes, making it an essential tool for modern web development.
B. Importance of grid-template-rows
The grid-template-rows property allows developers to define the heights of the rows in a grid container. This is crucial for creating visually appealing designs that can respond to different content sizes and screen dimensions.
II. Definition
A. What is grid-template-rows?
grid-template-rows is a CSS property used in a grid container to specify the height of each row. It accepts various values that determine how space is allocated vertically within the grid.
III. Syntax
A. Syntax structure of grid-template-rows
The basic syntax for grid-template-rows is as follows:
grid-template-rows: value1 value2 ... valueN;
B. Examples of syntax usage
Here’s a simple example that defines three rows with different heights:
.grid-container {
display: grid;
grid-template-rows: 100px 200px 300px;
}
IV. Values
A. Length values
Length values can be used to set fixed heights for rows, such as pixels (px) or ems. For example:
grid-template-rows: 150px 250px;
B. Percentage values
Percentage values define row height relative to the container’s height:
grid-template-rows: 50% 50%;
C. Fractional units (fr)
The fr unit divides available space in the container. For example:
grid-template-rows: 1fr 2fr;
D. Auto keyword
The auto keyword allows rows to size according to their content:
grid-template-rows: auto auto;
E. Min-content and max-content
The min-content and max-content keywords adjust row heights based on the content size constraints:
grid-template-rows: min-content max-content;
F. Repeat function
The repeat() function is helpful for creating multiple rows of the same height:
grid-template-rows: repeat(3, 100px);
G. Fit-content function
The fit-content() function allows you to set a height that fits the content without exceeding a maximum value:
grid-template-rows: fit-content(200px) 1fr;
V. Browser Support
A. Compatibility with different browsers
grid-template-rows is widely supported across modern browsers, including:
| Browser | Supported Version |
|---|---|
| Chrome | 57+ |
| Firefox | 52+ |
| Safari | 10.1+ |
| Edge | 16+ |
| IE | Not Supported |
VI. Related Properties
A. grid-template-columns
The grid-template-columns property complements grid-template-rows by defining the widths of columns in a grid:
grid-template-columns: 1fr 2fr 1fr;
B. grid-template
The grid-template property is a shorthand for defining both row and column sizes:
grid-template: 100px 200px / 1fr 2fr;
VII. Examples
A. Practical examples of grid-template-rows in use
Here’s a simple responsive example using grid-template-rows:
In this example, the grid has three rows where the header height adapts to the content, the main content row takes up a fraction of the available space, and the footer takes twice that space relative to the second row.
Another example showcasing the usage of repeat and fractional units:
This will create three equal rows in the grid, fully utilizing the available vertical space.
