In CSS, you can use the overflow attribute to hide multi-line text overflow. You only need to add the "overflow: hidden;" style to the text element. The overflow attribute specifies what happens when content overflows the element box. When the value is set to "hidden", the overflow part is set to be invisible.

In CSS, you can use the overflow attribute to hide multi-line text overflow.

The overflow attribute specifies what happens when content overflows the element box.

This attribute defines how content that overflows the element's content area will be handled. Property value:

hidden: The content will be trimmed and the remaining content will be invisible.
scroll: The content is trimmed, but the browser displays scroll bars to view the rest of the content.
auto: If content is trimmed, the browser displays scroll bars to view the remaining content.

If the value is scroll, the user agent will provide a scrolling mechanism whether required or not. Therefore, it is possible that scrollbars will appear even if everything fits inside the element box.

Example:

<!DOCTYPE html>
<html>
	<head>
		<meta charset="utf-8">
		<style type="text/css">
			div {
				background-color: pink;
				width: 150px;
				height: 150px;
				overflow: hidden
			}
		</style>
	</head>

	<body>
	<p>如果元素中的内容超出了给定的宽度和高度属性，overflow 属性可以确定是否显示滚动条等行为。</p>

	<div>
	这个属性定义溢出元素内容区的内容会如何处理。如果值为 scroll，不论是否需要，
	用户代理都会提供一种滚动机制。因此，有可能即使元素框中可以放下所有内容也会出现滚动条。
	默认值是 visible。
	</div>
	</body>

</html>
