html - header 上的未知样式

Question

关于 my website ，我的页眉和菜单之间显示了 80 像素的边距。这在首页上不是问题，只是在使用标准网站标题的博客上。

当我用谷歌检查它时，它说这是 div 上带有类自定义 header 的元素样式，而不是 CSS 的一部分。我正在使用 WordPress Twenty Sevente 的子主题。我查看了 CSS，但没有看到它说要添加边距的地方。我查看了 header-image.php 并没有找到任何东西。请注意，标题图片下方的边距在移动 View 中消失了。这是我在 child 和二十七岁时对 CSS/HTML 的了解:

子主题 CSS:

/*  Front Page: Header  */
.has-header-image .custom-header-media img,
.has-header-video .custom-header-media video,
.has-header-video .custom-header-media iframe {

    height: auto;
    left: 50%;
    max-width: 1000%;
    min-height: 100%;
    min-width: 100%;
    min-width: 100vw; /* vw prevents 1px gap on left that 100% has */
    width: auto;
    top: 50%;

Answer 1

似乎样式在一个单独的文件中。这应该可以解决您的问题:

@media(min-width: 768px) {
  .blog .custom-header {
    margin-bottom: 0;
  }
}

也许你必须使用 margin-bottom: 0; !重要
