调整浏览器大小时文本重叠导航栏 window

Question

我正在尝试为我的投资组合创建我的第一个网页，但我的文字一直与左侧的导航栏重叠，我不知道为什么！我尝试了不同的方法，但到目前为止没有任何效果，我只是不明白问题出在哪里！我是 HTML 和 CSS 的新手，所以我可能在没有意识到的情况下做错了:)

这是我的代码：

/* Heading Styles -----------------------*/

.main-header {
  padding-top: 0x;
  height: 250px;
  text-align: right;
}

#background-image {
  background: url("../banner/pilved.jpg") no-repeat center;
  background-size: cover;
}


/*Welcome to text------------------------------------*/

.first-line-title {
  font-size: 35px;
  color: white;
  font-weight: normal;
  font-style: italic;
  position: fixed;
  top: 30%;
  right: 35%;
}


/* AvesDEsign's portfolio text---------------------*/

.second-line-title {
  font-size: 90px;
  color: white;
  font-weight: normal;
  line-weight: 1.3;
  position: absolute;
  overflow: hidden;
  top: 40%;
  right: 8%;
}


/* Navigation bar -------------------------*/

* {
  margin: 0;
  padding: 0;
  font-family: Avenir;
}

nav {
  width: 250px;
  height: 600px;
  background-color: rgba(0, 0, 0, 0.2);
  line-height: 80px;
  text-align: center;
}

nav ul {
  float: left;
  margin-left: 45px;
  margin-top: -5px;
}

nav ul li {
  list-style-type: none;
  transition: 0.8s all;
  font-family: Avenir;
}

nav ul li:hover {
  background-color: #d0d6da;
}

nav ul li a {
  text-decoration: none;
  color: white;
  padding: 30px;
}


/* Logo information------------------------------*/

.logo {
  margin-left: -8px;
  margin-top: 40px;
}

<!doctype html>
<html lang="en">

<head>
  <title>AvesDesign</title>
  <link rel="stylesheet" href="css/style.css">
</head>

<body>
  <div id="background-image">
    <nav>
      <img class="logo" src="Logo/AvesDesignlogo.png" width="140" height="170" alt="AvesDesignlogo">
      <ul>
        <li><a href="#">HOME</a></li>
        <li><a href="#">PORTFOLIO</a></li>
        <li><a href="#">EXPERIENCE</a></li>
        <li><a href="#">CONTACT</a></li>
      </ul>
    </nav>

    <header class="main-header">
      <div class="first-line-title">Welcome to</div>
  </div>
  <div class="second-line-title">AvesDesign's portfolio
    </h1>

  </div>
  </header>
</body>

</html>

Answer 1

肯定会发现一些错误，但让我开始，您应该将 HTML 和 CSS 放在编辑器的指定区域，而不是单独的块。

在 HTML 中，您混淆了代码。 div 标签和 header 未正确关闭，因为关闭标签放置在错误的位置。您还缺少一个开头的 h1 标签。查看 HTML 代码并将其与您拥有的代码进行比较

下一步是将 position:relative 放在 main-header CSS 声明中。

.main-header {
  position: relative;
  padding-top: 0x;
  height: 250px;
  text-align: right;
}

进行这些更改，您可能会朝着正确的方向飞跃。

/* Heading Styles -----------------------*/

.main-header {
  position: absolute;
  width: 100%;
  top: 0;
  height: 250px;
  text-align: right;
  z-index: 0;
}

#background-image {
  background: url("../banner/pilved.jpg") no-repeat center;
  background-size: cover;
}


/*Welcome to text------------------------------------*/

.first-line-title {
  font-size: 35px;
  color: red;
  font-weight: normal;
  font-style: italic;
  /* CHANGE POSITION FROM FIXED TO ABSOLUTE */
  position: absolute;
  top: 30%;
  right: 35%;
}


/* AvesDEsign's portfolio text---------------------*/

.second-line-title {
  font-size: 40px;
  color: green;
  font-weight: normal;
  line-height: 1.3;
  position: absolute;
  overflow: hidden;
  top: 40%;
  right: 8%;
}


/* Navigation bar -------------------------*/

* {
  margin: 0;
  padding: 0;
  font-family: Avenir;
}

nav {
  position: relative;
  float: left;
  width: 250px;
  height: 600px;
  background-color: rgba(0, 0, 0, 0.8);
  line-height: 80px;
  text-align: center;
  z-index: 999;
}

nav ul {
  padding: 0;
  margin-left: 45px;
  margin-top: -5px;
  z-index: 9999;
}

nav ul li {
  list-style-type: none;
  transition: 0.8s all;
  font-family: Avenir;
}

nav ul li:hover {
  background-color: #d0d6da;
}

nav ul li a {
  text-decoration: none;
  color: white;
  padding: 30px;
}


/* Logo information------------------------------*/

.logo {
  margin-left: -8px;
  margin-top: 40px;
}
