How to implement irregular grid layout through CSS Flex elastic layout

In web design, it is often necessary to use grid layout to achieve page segmentation and layout. Usually grid layouts are regular and each grid is the same size, but sometimes we may need to implement some irregular grid layouts.

CSS Flex Flex Layout is a powerful layout method that can easily implement various grid layouts, including irregular grid layouts. Below we will introduce how to use CSS Flex elastic layout to implement irregular grid layout, and provide specific code examples.

First, we need to create an HTML structure. You can use the dc6dce4a544fdca2df29d5ac0ea9906b element or other container element as a grid container, and then create multiple sub-elements within the container. These sub-elements The element is the grid we want to lay out.

For example, we create a dc6dce4a544fdca2df29d5ac0ea9906b element named "grid-container" as a grid container, which contains three child elements, namely "item1" and "item2" and "item3":

<div class="grid-container">
  <div class="item item1">Item 1</div>
  <div class="item item2">Item 2</div>
  <div class="item item3">Item 3</div>
</div>

Next, we need to set CSS styles for the grid container and child elements, use display: flex to set the grid container as a flexible container:

.grid-container {
  display: flex;
  flex-wrap: wrap;
}

.item {
  flex: 1 0 auto;
}

In the above code, the flex-wrap: wrap attribute implements automatic line wrapping. When the width of the grid container is not enough to accommodate all child elements, it will automatically wrap and display. And flex: 1 0 auto can make each child element the same size.

In order to achieve irregular grid layout, we can also use the flex-grow and flex-basis attributes to control the scaling ratio and base size of sub-elements respectively. .

For example, if we want the first child element "item1" to occupy twice the width of the original grid container, we can set its flex-grow to 2, while the other child elements remain Default 1:

.item1 {
  flex-grow: 2;
}

Similarly, if we want the third child element "item3" to be twice as wide as the other child elements, we can set its flex-basis to 200% :

.item3 {
  flex-basis: 200%;
}

Through the above code settings, we can achieve irregular grid layout. The complete CSS code is as follows:

.grid-container {
  display: flex;
  flex-wrap: wrap;
}

.item {
  flex: 1 0 auto;
}

.item1 {
  flex-grow: 2;
}

.item3 {
  flex-basis: 200%;
}

The above is a detailed introduction and specific code examples on how to use CSS Flex elastic layout to implement irregular grid layout. By flexibly using various properties of CSS Flex layout, we can easily implement various unique grid layouts and improve the visual effects and user experience of the page.
