Whenever we work with a CSS grid, one of the questions that might come to mind is why, in some cases, the grid automatically expands to full width. This behavior is primarily due to the nature of how grids and CSS are designed. In HTML and CSS, block-level elements by default stretch to fill their parent container. Therefore, a grid container, which is a block-level element, exhibits the same behavior.
When you create a grid container without specifying a particular width for it, the boundaries automatically stretch to the full width of the parent page. This behavior is designed to create a coherent experience for users, which is quite familiar and typically occurs in most browsers by default.
Similarly, CSS features such as grid-template-columns and grid-template-rows used to define the structure of the grid can be tailored to match different dimensions of display pages. This feature significantly helps designers in responsive design.
However, if you find in your design that a specific grid has certain dimensions and shouldn't be expanded beyond that, it will return to the dimensions set for your container. You can easily do this by using the max-width property or specifying a particular width for the grid container itself.
Ultimately, the behavior of the grid is meant to be flexible and customizable, which is part of its attractiveness. You can adjust the values specifically for each instance based on your design requirements.
<div class="grid-container">
<div class="grid-item">1</div>
<div class="grid-item">2</div>
<div class="grid-item">3</div>
</div>
<style>
.grid-container {
display: grid;
grid-template-columns: repeat(3, 1fr);
}
</style>
<div class="grid-container"> - defines a container that will be grid-based
<div class="grid-item">1</div> - individual items contained within the grid
<style> ... </style> - the section that specifies styles related to CSS
display: grid; - specifies this container as a grid layout
grid-template-columns: repeat(3, 1fr); - configures three columns in the grid layout
