为什么导航栏不在网站顶部？

Question

我目前正在通过创建一个简单的网站来练习 html 和 css。

我的问题是无法将导航栏放在网站上方。我认为问题出在 header 或背景视频上。这是图片以获取更多详细信息。 Click here

我认为当导航栏被解析时，游戏段落将在它自己的位置。

现在这是我的 html 和 css 代码。

body{
    background: rgba(236,232,225,255);

我不确定某些代码的使用是否正确，但您也可以教我正确使用代码。感谢您的帮助 :>

Answer 1

如果我是你，我也会将我的徽标放在我的导航栏中（如果你要将它放在那里的话）。要将它放在顶部并留在那里，您可以使用 position: absolute。现在您还可以将其固定，这样当您滚动时它会停留在顶部。我编辑了您的代码，将其添加到您的 css 中，它将用作固定导航。

nav, #navname {
    position: fixed;
    top: 0;
}

#navname {
    position: absolute;
    left: 0;
}

.navlinks {
    position: fixed;
    right: 20px;
    top: 50px;
}

Answer 2

是因为你把导航条放在h1标签后面才这样的。创建一个 header 标签并将 h1 与 navname id 放在一起，然后将您的导航放在上述 header 标签中。我在您的代码中添加了一些 CSS 样式。检查并在您认为合适的项目中实施它。

body {
  background: rgba(236, 232, 225, 255);
  color: #333;
  font-family: helvetica;
  font-size: 15px;
  line-height: .5cm;
  margin: 0;
  padding: 0;
}

header {
  align-content: center;
  display: flex;
  justify-content: space-around;
  align-items: center;
  background-color: white'

}


/* links configuration here */

a {
  text-decoration: none;
  color: rgba(216, 108, 108, 0.932);
}

a:hover {
  color: blue;
}


/* links configuration ends here */

#webname {
  /* heading here */
  padding-top: 15%;
  padding-bottom: 15%;
  text-align: center;
  font-size: 150px;
  font-family: VALORANT;
  color: white;
}

#navname {
  /* navigation bar name */
  font-size: 75px;
  font-family: VALORANT;
  color: rgba(216, 108, 108, 0.932);
  float: left;
  padding-left: 30px;
  -webkit-text-fill-color: rgba(216, 108, 108, 0.932);
  -webkit-text-stroke: 1px white;
}

.navlinks {
  list-style-type: none;
  margin: 0;
  overflow: hidden;
  font-size: 20px;
}

.navlinks li {
  /* navigation links */
  float: right;
}

.navlinks a {
  display: block;
  text-align: center;
  padding: 14px 16px;
  font-size: 40px;
}

#videoBG {
  /* background vid */
  position: absolute;
  right: 0;
  bottom: 30%;
  min-width: 100%;
  min-height: 100%;
  width: auto;
  height: auto;
  z-index: -100;
  background-size: cover;
  overflow: hidden;
}

@media (min-aspect-ratio: 16/9) {
  #videoBG {
    width: 100%;
    height: auto;
  }
}

@media (max-aspect-ratio: 16/9) {
  #videoBG {
    width: auto;
    height: 100%;
  }
}

@media (max-width: 767px) {
  #videoBG {
    display: none;
  }
  body {
    background: url('valoClip.png');
    background-size: cover;
  }
}

@font-face {
