CSS CSS Grid How to Select Rows and Add Hover Effects

In this article, we’ll cover how to select rows and add hover effects using CSS Grid. CSS Grid is a powerful layout system that allows you to create grid structures in a flexible way, allowing you to easily define the rows and columns of a grid. However, since CSS Grid doesn’t directly provide a way to select rows, you need to use some tricks to achieve this.

Selecting Rows with grid-template-areas

A common way to select rows is by using the grid-template-areas property. We can define a unique grid area for each row, and then select the corresponding row based on the area name. By adding a hover effect to the selected row, we can change the appearance of the row by setting the corresponding CSS style.

First, we need to define the grid layout in CSS and add the grid-template-areas property to each row. For example, if we have three rows, we can define them like this:

.grid-container {
display: grid;
grid-template-rows: repeat(3, 1fr); /* Set 3 rows, each with a height of 1fr */
grid-template-areas:
"row1"
"row2"
"row3";
}

Next, we can add corresponding area names to the elements of each row, for example:

<div class="grid-container">
<div class="row1">First row</div>
<div class="row2">Second row</div>
<div class="row3">Row 3</div>

</div>

We can then use CSS selectors to select specific rows and add hover effects to them. For example, we can use the :hover pseudo-class to add a background color to the selected rows:

.grid-container .row1:hover {
background-color: yellow;
}

.grid-container .row2:hover {
background-color: orange;
}

.grid-container .row3:hover {
background-color: green;
}

In this way, we can select specific rows and add a specific effect to them when hovered.

Selecting Rows with the grid-row Property

In addition to using the grid-template-areas property to select rows, we can also use the grid-row property. The grid-row property allows us to specify the start and end positions of a row, thereby selecting specific rows.

First, we need to assign a unique class name or ID to each row element. For example, we could assign the class names row1, row2, and row3 to each row element.

<div class="grid-container"> 
<div class="row1">First row</div> 
<div class="row2">Row 2</div>
<div class="row3">Row 3</div>

</div>

Then, in CSS, we can use the grid-row property to select specific rows. For example, if we want to select row 1 (from row 1 to row 1 end), we can write the CSS style like this:

.grid-container .row1 {
grid-row: 1 / 2;
}

Similarly, if we want to select row 2, we can write the CSS style like this:

.grid-container .row2 {
grid-row: 2 / 3;
}

And so on.

This way, we can select specific rows and add hover effects or other styling as needed.

Summary

Although CSS Grid doesn’t directly provide a row selection feature, we can use the grid-template-areas or grid-row properties to select specific rows and add hover effects or other styling. Using these techniques, we can better control and layout the grid and provide users with a richer interactive experience.

In practice, you can choose the appropriate method to select rows and add corresponding effects based on your specific needs and layout design. I hope this article helps you learn and use CSS Grid!
