AtoZ CSS Quick Tip: Using Widows and Line Breaks
Article Introduction：Key Points
Avoid using the tag to force line wrapping, as this will cause text to appear inconsistently at different screen sizes. CSS is recommended to control spacing and line breaks, which provides better control and flexibility.
Use the display attribute to display or hide newlines. Setting display: none will not produce a line break, while display: block will produce a line break. In conjunction with media queries, line breaks can be enabled or disabled under specific screen sizes.
To avoid widow lines (single words at the end of a paragraph or title), use line-breaking space characters (?) between the last two words. This ensures that the last two words are processed as one word, creating a more beautiful line break effect.
