Here's what's going on css code
body{ font-size: 14px; color: black; background-color: #ccc; font-family:
Arial, Helvetica, sans-serif," Microsoft YaHei "; line-height: 1.5; } <!-- Here is to set some properties for the whole page
font size background color Font color And fonts Xinggao It's all global --> a{ color: #00a1d6; text-align: center; }
<!-- This is for the overall situation a Set some styles for labels --> .main{ width: 220px; border: 1px solid #eee; margin
: 10px auto; box-sizing: border-box; } <!-- It's for the main one div Set style Fixed width Set borders, etc Center it and so on -->
.main ul li{ border: 1px solid #eee; line-height: 50px; height: 50px; <!--
This is the middle Row height and height are equal -->background-color:#fff; position: relative; text-align:
center; <!-- Center text --> box-sizing: border-box; } .main ul li ul{ display: none;
<!-- Here is the hidden meaning -->position: absolute; left: 218px; top: -3px; width: 120px;
height: 50px; border: 1px solid #ccc; box-sizing: border-box; } .main li:hover{
