Detailed explanation of CSS column width properties: column-width and column-count

Detailed explanation of CSS column width attributes: column-width and column-count, specific code examples are required

In web design, we often need to divide content into multiple columns , to improve the presentation of information. The column layout properties in CSS provide us with flexible solutions. Among them, column-width and column-count are two commonly used column width attributes. This article details the usage of these two properties and provides corresponding code examples.

1. Column-width attribute

The column-width attribute is used to set the width of each column. The syntax is as follows:

div {
  column-width: value;
}

Among them, value can be a specific width value, such as pixels (px), percentage (%), automatic (auto), or keywords such as inherit, initial, etc.

Code example:

<div class="container">
  <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed mattis est id sem consequat, sit amet lobortis arcu bibendum.</p>
  <p>Integer ut sapien nec lectus euismod interdum. Vestibulum efficitur est massa, nec accumsan eros cursus eget.</p>
  <p>Donec eleifend eros eget enim eleifend, ac sollicitudin libero aliquam. Suspendisse potenti. Aliquam eget placerat mi.</p>
</div>

<style>
.container {
  column-width: 200px;
}
</style>

The above code divides a container div into three columns, each column is 200px wide. If the container is not wide enough to accommodate three columns, the browser will automatically adjust the width of the columns to fit within the container.

2. Column-count attribute

The column-count attribute is used to set the number of columns. The syntax is as follows:

div {
  column-count: value;
}

Among them, value represents the number of columns, which can be a specific number or a keyword, such as auto, inherit, initial, etc.

Code example:

<div class="container">
  <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed mattis est id sem consequat, sit amet lobortis arcu bibendum.</p>
  <p>Integer ut sapien nec lectus euismod interdum. Vestibulum efficitur est massa, nec accumsan eros cursus eget.</p>
  <p>Donec eleifend eros eget enim eleifend, ac sollicitudin libero aliquam. Suspendisse potenti. Aliquam eget placerat mi.</p>
</div>

<style>
.container {
  column-count: 2;
}
</style>

The above code divides the container div into two columns. If the content in the container exceeds the width that the two columns can accommodate, the browser will automatically divide the content into the next column. .

3. Combination of column-width and column-count

column-width and column-count can be used together to achieve more complex column layout. When using the column-count attribute, the number of columns takes precedence over the column width attribute, and the browser will automatically calculate the column width to fill the container.

Code example:

<div class="container">
  <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed mattis est id sem consequat, sit amet lobortis arcu bibendum.</p>
  <p>Integer ut sapien nec lectus euismod interdum. Vestibulum efficitur est massa, nec accumsan eros cursus eget.</p>
  <p>Donec eleifend eros eget enim eleifend, ac sollicitudin libero aliquam. Suspendisse potenti. Aliquam eget placerat mi.</p>
</div>

<style>
.container {
  column-count: 3;
  column-width: 200px;
}
</style>

The above code divides the container div into three columns, each column has a width of 200px. If the container width is not enough to accommodate three columns, the browser will automatically adjust the width of the columns to Adapt to the container.

Summary:

In web design, using the column-width and column-count properties can easily achieve multi-column layout effects. By setting the column width and number of columns, you can make the page content more organized and improve the user experience.
