Question

我有这个问题，现在我已经知道了关于html和css的基础知识，我接受了挑战来设想这个网页的外观，但是我做了一些事情并知道地址栏和菜单之间有空格，我尝试过很多东西，但我仍然没有解决问题。

非常感谢任何帮助我的人

CSS Index
body{
    overflow: hidden;
}
.main{
    position: relative;
    margin: 70px auto;
    width: 90%;
    max-width: 1080px;
    height: auto;
    z-index: 480;
}

.contenedor-destacados{
    width: 100%;
    text-align: center;
    background-color: rgba(232, 236, 237, 0.29);
    display: block;
    position: relative;
    top: 40px;
    border-radius: 10px;
}

.title-destacados{
    display: block;
    text-align: center;
    /*padding: 10px;*/
    color: rgb(50, 50, 50);
    letter-spacing: 1.3px;

Answer 1

我认为这是因为在.main你有

margin: 70px auto

我不知道您的网页，所以可能不是这样，但请尝试更改为margin: 0 auto

更新：请从top:40px

中删除.contenedor-destacados

Answer 2

您需要添加top:0;

header {
    width: 100%;
    box-sizing: border-box;
    display: block;
    height: 15px;
    position: absolute;
    background-color: rgb(3, 3, 3);
    z-index: 1000;
    top: 0;
}

头和菜单之间的空白
