First of all, I would like to thank winter-CN for pointing out one error after another in the design mode application. Without him, I will continue to make many mistakes. In addition, I would like to thank many park frie

It actually achieves the minimum width by JavaScript's judgment.3 ie hide and seek problemsWhen the div application is complex, there are some links in each column, and the div is prone to hide-and-seek problems.Some content does not show up when the mouse selects this area is found content is indeed on the page.WORKAROUND: Use Line-height attribute for #layout or use fixed height and width for #layout. The page structure is as simple
