保证金/填充不起作用

Question

我在主div中有2个主要的div。我已经尝试添加大量的边距和填充来测试，但它只是工作。为什么我不能在它们之间添加边距/填充？请帮忙。

Answer 1

好的，所以我认为您已尝试向.brandList div添加保证金和填充，该display: inline div具有display: inline-block属性。将其更改为:- use_module(library(clpfd)). gsudoku([],_). gsudoku([e(F,T)|XS],N):- F in 1.. N, T in 1.. N , F #\= T , gsudoku(XS,N). ，边距和填充应该有效。 （检查：http://tympanus.net/codrops/css_reference/display/）。

Answer 2

margin在嵌入式HTML元素上不起作用。如果要在行内元素上应用边距，则必须通过应用display: inline-block属性将目标元素转换为块级元素。
