30秒学会 CSS 片段 – Trim multiline text

Limit multiline text to a given number of lines.

• Use -webkit-line-clamp to set the maximum number of lines to be displayed.
• Set display to -webkit-box and -webkit-box-orient to vertical, as they are required for -webkit-line-clamp to be applied.
• Apply overflow: hidden to hide any overflow after the text is trimmed.
