The following will explain in detail how to use the :last-child pseudo-class selector and provide specific code examples.

First, let us understand the basic syntax and usage of the :last-child pseudo-class selector. The :last-child selector can be used to select the last child element in the parent element. For example, if there are multiple child elements in a parent element, we can use the :last-child pseudo-class selector to select the last child element and add styles to it. The following is the basic syntax of the last-child pseudo-class selector:

Parent element: last-child {

/* 添加样式 */

Next, let us pass a specific Example to illustrate how to use the :last-child pseudo-class selector. Suppose we have an HTML structure that looks like this:

<div class="parent">
    <span>第一个子元素</span>
    <span>第二个子元素</span>
    <span>第三个子元素</span>
    <span>最后一个子元素</span>
</div>

Now, we want to select the last child element within the parent element and add a specific style to it. We can use the :last-child pseudo-class selector to achieve this effect. The following is a specific CSS code example:

.parent span:last-child {
    color: red;
    font-weight: bold;
}

In the above code example, we use the .parent span:last-child selector to select .parent The last span child element in the element and apply a red color and bold font style to it. This way, the last child element within the parent element will become red and bold.

For example, we can add normal styles to the first three child elements and highlight styles to the last child element. The following is a specific CSS code example:

.parent span:not(:last-child) {
    color: blue;
}
.parent span:last-child {
    color: red;
    font-weight: bold;
}

In the above code example, the :not(:last-child) selector is used to select except the last child in the .parent element All child elements outside the element and apply a style with color blue to them. At the same time, the .parent span:last-child selector is used to select the last span child element in the .parent element and apply the color to it. Red, bold font style.
