This paper explores how to eliminate <br> tags and achieve line breaks for inline-block elements through pure CSS in web layout. Traditional methods, such as setting elements to display:block, cause the width to expand to 100%, while display:inline-block maintains content width but lacks automatic line breaks. The focus is on the advantages of the display:table property, which combines the line-breaking behavior of block-level elements with automatic width adaptation to content, without requiring explicit width settings. Additionally, the paper compares alternative approaches like float:left and clear:left, explaining the superiority of display:table in terms of semantics and layout flexibility. Through code examples and principle analysis, this paper provides an efficient and maintainable CSS layout solution for front-end developers.
