What is the difference between grid-auto-rows and grid-template-rows?
What is the difference between grid-auto-rows and grid-template-rows?
Jun 26, 2025 am 12:42 AM
grid-template-rows is used to explicitly define the height of grid rows, while grid-auto-rows controls the height of implicit rows automatically created by the browser. 1. grid-template-rows is to manually set the fixed number and height of rows, suitable for known structures such as the header, body, and footer; 2. grid-auto-rows is to set the default row height for dynamic content beyond the definition range, and is used to handle uncertain number of data lists; 3. The two can be used together to enhance layout flexibility. For example, the first two rows are defined by grid-template-rows, and subsequent rows are controlled by grid-auto-rows.
In CSS Grid layouts, grid-auto-rows and grid-template-rows look similar, but they do completely differently. Simply put, grid-template-rows is the row height you explicitly define for the grid, while grid-auto-rows is the default height of the extra rows automatically created by the browser.
grid-template-rows: The area you plan manually
When you use grid-template-rows , you are telling the browser: "How many lines do I have on this page, how high each line is". for example:
.grid {
display: grid;
grid-template-rows: 100px 200px 150px;
}This code creates a three-line grid layout, the first line is 100px high, the second line is 200px, and the third line is 150px. These are the lines you clearly define.
If you put more than three rows of content, the content will continue to line down by default. At this time, it is grid-auto-rows turn to appear.
grid-auto-rows: How to arrange automatically created rows
When your grid content is more than the number of rows you define with grid-template-rows , the browser will automatically create "implicit" rows. The height of these rows is controlled by grid-auto-rows .
for example:
.grid {
display: grid;
grid-template-rows: 100px 200px;
grid-auto-rows: 150px;
}In this example, the first two lines are fixed 100px and 200px. If there is more, each line in the following will be 150px high.
You can understand it as: "The remaining lines, follow this rule."
Use scenarios and suggestions
- Use
grid-template-rowsto control structures you know clearly , such as layouts such as header, body, and footer. - Use
grid-auto-rowsto process dynamic content , such as the list of data obtained from the backend, and the amount is uncertain.
Let me give you a practical example:
- If you are making a dashboard, set several fixed blocks on the top with
grid-template-rows; - The following data cards may have dozens of them, and the height of each one is set uniformly using
grid-auto-rows.
It can also be used in combination, such as:
.grid {
display: grid;
grid-template-rows: 80px auto;
grid-auto-rows: 60px;
}This means that the first two lines are 80px and automatic height respectively, and the excesses are 60px by default for each line.
Basically that's it. Understanding the difference between these two attributes will allow you to more flexibly control the layout behavior of CSS Grid.

CSS tutorial for creating loading spinners and animations

Setting the style of links you have visited can improve the user experience, especially in content-intensive websites to help users navigate better. 1. Use CSS's: visited pseudo-class to define the style of the visited link, such as color changes; 2. Note that the browser only allows modification of some attributes due to privacy restrictions; 3. The color selection should be coordinated with the overall style to avoid abruptness; 4. The mobile terminal may not display this effect, and it is recommended to combine it with other visual prompts such as icon auxiliary logos.

To create responsive images using CSS, it can be mainly achieved through the following methods: 1. Use max-width:100% and height:auto to allow the image to adapt to the container width while maintaining the proportion; 2. Use HTML's srcset and sizes attributes to intelligently load the image sources adapted to different screens; 3. Use object-fit and object-position to control image cropping and focus display.

Demystifying CSS Units: px, em, rem, vw, vh comparisons
Jul 08, 2025 am 02:16 AM
The choice of CSS units depends on design requirements and responsive requirements. 1.px is used for fixed size, suitable for precise control but lack of elasticity; 2.em is a relative unit, which is easily caused by the influence of the parent element, while rem is more stable based on the root element and is suitable for global scaling; 3.vw/vh is based on the viewport size, suitable for responsive design, but attention should be paid to the performance under extreme screens; 4. When choosing, it should be determined based on whether responsive adjustments, element hierarchy relationships and viewport dependence. Reasonable use can improve layout flexibility and maintenance.
What are common CSS browser inconsistencies?
Jul 26, 2025 am 07:04 AM
Different browsers have differences in CSS parsing, resulting in inconsistent display effects, mainly including the default style difference, box model calculation method, Flexbox and Grid layout support level, and inconsistent behavior of certain CSS attributes. 1. The default style processing is inconsistent. The solution is to use CSSReset or Normalize.css to unify the initial style; 2. The box model calculation method of the old version of IE is different. It is recommended to use box-sizing:border-box in a unified manner; 3. Flexbox and Grid perform differently in edge cases or in old versions. More tests and use Autoprefixer; 4. Some CSS attribute behaviors are inconsistent. CanIuse must be consulted and downgraded.
