如何将菜单栏与div中的正文分开,将其后的所有内容放在其下方,是否有相应的代码如换行符?我真的很感激帮助:)在此先感谢 这是一张照片的链接:
CSS
/* because of the * default code it takes out all margin and padding */
* {
margin: 0px;
padding: 0px;
}
#container {
display: table;
}
#row {
display: table-row;
}
#left, #right, #middle {
display: table-cell;
}
#row {
display: table-row;
}
#left, #right, #middle {
display: table-cell;
}
body {
font-family: verdana;
font-size: 10px;
background-color: ABC;
padding: 50px;
margin: auto;
}
h1 {
text-align: center;
}
ul {
list-style: none;
margin: 0;
padding: 0;
}
li {
float: left;
position: relative;
}
li + li {
border-left: 1px solid #ccc;
}
a {
display: block;
padding: 7px 10px;
color: #222; /*changes the color of all item font color in menu bar */
background: #eee; /*changes the background color of Menu bar */
text-decoration: none;
}
a:hover {
color: #fff;
background: #666; /* changes hover bg color of any menu item being pointed*/
}
a:active {
color: #f2f75e;
background: #0090cf;
}
/* Child Menu Styles */
.level-two {
position: absolute;
top: 100%;
left: -9999px;
width: 100px;
}
li:hover .level-two {
left: 0;
}
.level-two li {
width: 100%;
border: 0;
border-top: 1px solid #ccc;
}

clear
属性的一个替代方法是在菜单上触发新的块格式化上下文,以便在.level-one
中包含浮点数:
.level-one {
/* trigger block formatting context to contain floats. */
overflow: hidden;
}

Here is a list of other property/value pairs that trigger block formatting context

clear属性会为您执行此操作。您可以将其添加到#container
,例如:
#container {
display: table;
clear:both;
}
清除意味着:
清除此元素两侧的所有元素
