1. 技術選型
2. 搭建相關資料夾結構
3. 引入視口標籤以及初始化樣式
4. 常用初始化樣式
5. 首頁佈局分析以及搜尋模組佈局
index.css
/*搜尋模組*/ .search-index{ /*固定定位跟父級沒有關係,它以螢幕為準*/ position: fixed; top: 0; left: 50%; /*固定的盒子應該有寬度*/ -webkit-transform: translateX(-50%); transform: translateX(-50%); width: 100%; min-width: 320px; max-width: 540px; height: 44px; background-color: pink; }
index.html
<!--頂部搜尋-->
<div class="search-index">
</div>
6. 搜尋模組劃分以及 user模組製作
index.html
<div class="search-index">
<div class="search"></div>
<a class="user">我 的</a>
</div>
index.css
/*搜尋模組*/ .search{ flex: 1; /*background-color: red;*/ } /*使用者模組*/ .user { background-color: purple; width: 44px; height: 44px; text-align: center; font-size: 12px; color: #2eaae0; } /*使用者頭像*/ .user::before{ content: ""; background: url("../images/sprite.png") no-repeat -59px -194px; background-size: 104px auto; width: 23px; height: 23px; display: block; margin: 5px auto 0; }
7. 搜尋模組製作
index.html
<div class="search-index">
<div class="search">搜尋:目的地/酒店/景點/航班號</div>
<a class="user">我 的</a>
</div>
index.css
/*使用 css3 盒子模型來做*/ div { box-sizing: border-box; } /*search-index模組*/ .search-index{ /*固定定位跟父級沒有關係,它以螢幕為準*/ position: fixed; top: 0; left: 50%; /*固定的盒子應該有寬度*/ -webkit-transform: translateX(-50%); transform: translateX(-50%); width: 100%; min-width: 320px; max-width: 540px; height: 44px; /*background-color: pink;*/ background-color: #F6F6F6; border-top: 1px solid #ccc; border-bottom: 1px solid #ccc; display: flex; } /*search模組*/ .search{ flex: 1; /*background-color: red;*/ height: 26px; line-height: 24px; font-size: 12px; border-radius: 5px; margin: 7px 10px; padding-left: 25px; box-shadow: 0 2px 4px rgba(0,0,0, .2); position: relative; } .search::before{ content: ""; /*display: block;*/ position: absolute; top: 5px; left: 5px; width: 15px; height: 15px; background: url("../images/sprite.png") no-repeat -59px -279px; background-size: 104px auto; }
8.焦點圖 focus 的製作
index.html
<!--焦點圖模組-->
<div class="focus">
<img src="upload/focus.jpg">
</div>
index.css
/*焦點圖模組*/
.focus {
padding-top: 44px;
}
.focus img {
width: 100%;
}
9. local-nav佈局
index.html
<!--區域性導航欄-->
<div class="local-nav">
<li>1</li>
<li>2</li>
<li>3</li>
<li>4</li>
<li>5</li>
</div>
index.css
li {
margin: 0;
padding: 0;
list-style: none;
}
/*區域性導航欄模組*/
.local-nav{
background-color: #fff;
height: 64px;
border-radius: 5px;
margin: 3px 4px;
display: flex;
}
.local-nav li {
flex: 1;
}
10. 常見flex 佈局思路
栗子:
第一步:預設主軸是 x 軸
index.html
<li>
<a>
<span class="local-nav-icon"></span>
<span>景點·玩樂</span>
</a>
</li>
index.css
.local-nav a {
display: flex;
}
.local-nav-icon{
width: 32px;
height: 32px;
background-color: pink;
}
第二步:把主軸設定為 y 軸
.local-nav a {
display: flex;
flex-direction: column;
}
第三步:把側軸設定為居中對齊
.local-nav a {
display: flex;
flex-direction: column;
/*這裡是單行的,沒有出現換行的情況,所以使用 align-items*/
align-items: center;
}
11. local-nav 內容製作
index.html
<!--區域性導航欄-->
<div class="local-nav">
<li>
<a title="景點·玩樂">
<span class="local-nav-icon"></span>
<span>景點·玩樂</span>
</a>
</li>
<li>
<a title="景點·玩樂">
<span class="local-nav-icon"></span>
<span>景點·玩樂</span>
</a>
</li>
<li>
<a title="景點·玩樂">
<span class="local-nav-icon"></span>
<span>景點·玩樂</span>
</a>
</li>
<li>
<a title="景點·玩樂">
<span class="local-nav-icon"></span>
<span>景點·玩樂</span>
</a>
</li>
<li>
<a title="景點·玩樂">
<span class="local-nav-icon"></span>
<span>景點·玩樂</span>
</a>
</li>
</div>
index.css
/*local-nav內容製作*/
.local-nav a {
display: flex;
flex-direction: column;
/*這裡是單行的,沒有出現換行的情況,所以使用 align-items*/
align-items: center;
font-size: 12px;
}
.local-nav-icon{
width: 32px;
height: 32px;
/*background-color: pink;*/
background: url("../images/localnav_bg.png") no-repeat 0 0;
background-size: 32px auto;
}
12. 利用屬性選擇器更換背景圖片
index.html
<div class="local-nav">
<li>
<a title="景點·玩樂">
<span class="local-nav-icon-icon1"></span>
<span>景點·玩樂</span>
</a>
</li>
<li>
<a title="景點·玩樂">
<span class="local-nav-icon-icon2"></span>
<span>景點·玩樂</span>
</a>
</li>
<li>
<a title="景點·玩樂">
<span class="local-nav-icon-icon3"></span>
<span>景點·玩樂</span>
</a>
</li>
<li>
<a title="景點·玩樂">
<span class="local-nav-icon-icon4"></span>
<span>景點·玩樂</span>
</a>
</li>
<li>
<a title="景點·玩樂">
<span class="local-nav-icon-icon5"></span>
<span>景點·玩樂</span>
</a>
</li>
</div>
index.css
.local-nav li [class^="local-nav-icon"]{
width: 32px;
height: 32px;
/*background-color: pink;*/
background: url("../images/localnav_bg.png") no-repeat 0 0;
background-size: 32px auto;
}
.local-nav li .local-nav-icon-icon2{
background-position: 0 -32px;
}
.local-nav li .local-nav-icon-icon3{
background-position: 0 -64px;
}
.local-nav li .local-nav-icon-icon4{
background-position: 0 -96px;
}
.local-nav li .local-nav-icon-icon5{
background-position: 0 -128px;
}

index.html
<!--選單欄部分-->
<nav>
<div class="nav-common">
<div class="nav-items">a</div>
<div class="nav-items">b</div>
<div class="nav-items">c</div>
</div>
<div class="nav-common">2</div>
<div class="nav-common">3</div>
</nav>
index.css
/*選單欄部分*/
nav {
border-radius: 8px;
margin: 0 4px 3px;
}
nav .nav-common{
/*width: 100%;*/
height: 88px;
background-color: pink;
border-radius: 3px;
display: flex;
}
/* -n+2就是選擇前面兩個元素 */
nav .nav-common:nth-child(2){
margin: 3px 0;
}
/*.nav-items部分*/
.nav-items{
flex: 1;
}
.nav-items:nth-child(-n+2){
border-right: 1px solid #ffffff;
}

<a>特價酒店</a>
</div>
</div>
<div class="nav-common">
<div class="nav-items">

index.css
/*.nav-items部分*/
.nav-items{
flex: 1;
display: flex;
/*這兩個是不衝突的*/
flex-direction: column;
}
.nav-items a {
flex: 1;
text-align: center;
line-height: 44px;
color: #ffffff;
}
.nav-common .nav-items:nth-child(1) a{
border-bottom: 0;
background: url("../images/hotel.png") no-repeat bottom center;
background-size: 121px auto;
}
.nav-items a:nth-child(1){
border-bottom: 1px solid #ffffff;
}
15. 背景線性漸變
栗子:
<style>
div{
width: 600px;
height: 200px;
background:-webkit-linear-gradient(left,red,blue);
}
</style>
<body>
<div></div>
</body>
注意: 背景漸變必須新增瀏覽器私有字首
-
從左到右的漸變:
background:-webkit-linear-gradient(left,red,blue);
-
不加方向 預設是從上往下的方向:
background:-webkit-linear-gradient(red,blue);
-
左上角到右下角的漸變:
background:-webkit-linear-gradient(top left,red,blue);
16. 設定nav 內容背景漸變
index.css
/*背景漸變*/
.nav-common:nth-child(1) {
background: -webkit-linear-gradient(left, #FA5A55, #FA994D);
}
.nav-common:nth-child(2) {
background: -webkit-linear-gradient(left, #4B90ED, #53BCED);
