Question

所以我的标题设置了背景图像，我想在其下创建一个div，以便可以在其中写文本，但是当我创建新的div时，我在其中写入的文本会显示在已经存在的顶部创建的标题。我认为这是由于我设置了背景图片。这是我自己完成的第一个项目，因此，如果你们能帮助我，我将不胜感激。

这些是HTML和CSS文件：

body {
	margin: 0;
	padding: 0;
	background-color:#f4f4f4;
	float: left;
}

header{
	overflow: hidden;
	margin: auto;
}

nav {
	width: 100%;
	height: 50px;
	background-color: rgba(192,192,192,0.3);
	margin: auto;
}


.wtf {
	padding-right: 50px;
	position: relative;
	bottom: 3px;
}

#logo {
	float: left;
	color: white;
	font-family: 'Concert One', cursive;
	padding-left: 20px;
}


p.highlight {
	margin: 0;
	position: relative;
	bottom: 7px;
}


ul {
	float:right;
}

li {
	display: inline;
	padding: 0 10px 0 10px;

	margin: 0 0 3px 0;
	font-family: 'Montserrat', sans-serif;
}

li a:hover {
  background-color: #ddd;
  color: black;
}

.image {

Answer 1

您绝对定位了.main：

.main {
    position: absolute;
}

使用这种样式，您可以从常规文档流中删除.main，并将其放在左上角。其他元素保持规则流动并在其上方。摆脱这种定位，您就可以开始了。

body {
	margin: 0;
	padding: 0;
	background-color:#f4f4f4;
	float: left;
}

header{
	overflow: hidden;
	margin: auto;
}

nav {
	width: 100%;
	height: 50px;
	background-color: rgba(192,192,192,0.3);
	margin: auto;
}


.wtf {
	padding-right: 50px;
	position: relative;
	bottom: 3px;
}

#logo {
	float: left;
	color: white;
	font-family: 'Concert One', cursive;
	padding-left: 20px;
}


p.highlight {
	margin: 0;
	position: relative;
	bottom: 7px;
}


ul {
	float:right;
}

li {
	display: inline;
	padding: 0 10px 0 10px;
}

a {
	text-decoration: none;
	color: white;
	font-size: 21px;
	margin: 0 0 3px 0;
	font-family: 'Montserrat', sans-serif;
}

li a:hover {
  background-color: #ddd;
  color: black;
}

.image {
	background-image: url('https://picsum.photos/200/300?image=15');
}

.main {
	width: 100%;
	height: 400px;
	color: white;
	text-align: justify;
	/* position: absolute; <-- do not position this absolutely */
	font-family: 'Montserrat', sans-serif;
	background-image: url('https://picsum.photos/1920/1080?image=10')
}

.main p,h1,h3 {
	text-align: center;
	position: relative;
}

.main h1 {
	top: 100px;
	font-size: 50px;
}

.main h3 {

Answer 2

您的.main css类具有绝对位置。禁用即可解决问题

Answer 3

从CSS中删除一些position属性。

.development {
    // remove
    //position: relative;
}

.main {
    width: 100%;
    height: 400px;
    color: white;
    text-align: justify;
   // remove 
   // position: absolute;
    font-family: 'Montserrat', sans-serif;
    background-image: url(nebula-stars-universe-galaxy-space-4k-kx-1920x1080.jpg);
}

可以切换到上方，但是您的body会向左浮动，因此也应将其删除。

body {
    margin: 0;
    padding: 0;
    background-color: #f4f4f4;
   // remove
   // float: left;
}

标头和div出现在同一行
