兼容css3新屬性css
在css3中,咱們可使用prefixfree.min.js這個插件來自動爲css3的相關屬性加上兼容瀏覽器屬性,使咱們不用爲每一個css3新屬性再加上屬性(須要用到大量css3的項目時再引入)html
content佈局css3
當h5內嵌在app裏面的時候,在iso手機下,底部(頭部)固定按鈕會跟着一塊兒滾動,須要使用content佈局,而後使用padding-bottom或者padding-top,把相應的位置空出來!!!web
當須要在content裏面滾動的時候,須要將body和html設置height:100%;而後content也須要設置height:100%,這樣才能夠實如今content裏面裏面滾動,當須要在body裏面滾動的時候,須要將html、body中的height:100%;設置去掉!!否則body會被限制住,內容只顯示一半不能滾動!!!ajax
還有一種解決彈窗遮罩層底部出現滾動的方法就是,當出現彈窗的時候,經過js控制底下的內容爲body{height:100%;overflow:hidden;},而後關閉彈窗的時候移除掉這個樣式!!!xcode
<body> <header></header> <div class="content"></div> <footer></footer> </body>
.content { padding-top: .88rem; -webkit-box-sizing: border-box; -moz-box-sizing: border-box; box-sizing: border-box; max-width: 750px; width: 100%; margin: 0 auto; overflow-x: hidden; height: 100%; overflow-y: auto; -webkit-overflow-scrolling: touch;
使用這種佈局方式能夠解決,單頁面滾動的時候,點擊彈窗,彈窗會被遮住滾動問題!!!瀏覽器
注意:當須要計算body的高度的時候,不能使用,還有當頁面中,有表單,須要使用position:relative時,來使安卓鍵盤不被擋住!!!!可是爲解決彈窗不滾動問題,能夠經過,彈窗的時候,增長content佈局,關閉彈窗的是移除content佈局!!!sass
//點擊領取 $(".reward-btn").click(function(){ $(".reward-page").wrap("<div class='contentS'></div>"); $(".insurance-box").show(); $(".dialog2").show(); }); //點擊關閉大彈窗按鈕 $(".closeDia").click(function(){ $(this).parent().parent().hide(); $(".dialog2").hide(); $(".reward-page").unwrap("<div class='contentS'></div>"); });
場景二:在content佈局下,須要給頁面設置背景圖,能夠在content下面在包裹一層大的div,而後對這個div進行全頁面背景圖設置,這樣背景圖纔會隨着內容超出一屏幕而滾動,而不是直接在content這個容器上設置背景圖,若是直接在這個容器上設置背景圖,那背景圖不會滾動!!!app
常見頭部佈局ide
兩邊有時候有文字或者圖標,可是中間的標題固定居中,大概位置以下,就是內容會變化!!
佈局以下
<div class="head"> <a class="head-left">設置</a>我的中心<a class="head-right">更多</a></div> css: .head{ position:relative; width:100%; height:88px; line-height:88px; text-align:center; } .head-left, .head-right{ position:absolute; height:88px; line-height:88px; } .head-left { left:30px; } .head-right { right:30px; }
模擬上拉加載
$(window).scroll(function() { var winH = $(window).height(); var scrH = $(window).scrollTop(); var htmH = $(document).height(); //解決滾動到下面,遮罩層一半 $(".fixed").height(htmH); if(winH + scrH >= htmH) { console.info(tabActive); if(tabActive==0){ console.info(1111); if(next_page){ if(ajax_lock == true) { ajax_lock = false; page++; getRecord(page,0); } } } });
1.美化複選框
效果
html代碼

css代碼
.hidden {
display: none;
}
.checkbox:checked ~.icon-checkbox {
background: url(../images/yes_15.png) no-repeat;
background-size: 0.3rem 0.25rem;
}
.icon-checkbox {
width: 0.3rem;
height: 0.3rem;
margin-right: 0.1rem;
border: 0.02rem solid #d7d7d7;
border-radius: 0.06rem;
}
.icon {
display: inline-block;
vertical-align: middle;
}
js if(!$('#agreeTerm').is(":checked")){ $.alert('請勾選贊成《保險條款》和《重要告知與申明》'); return; };
<div class="allCheck"> <input type="checkbox" id="allCheck" class="check hidden">
<label for="allCheck" class="check-icon">全選</label> </div>
.allCheck {
padding:0 .1rem 0 .3rem;

}
.check:checked ~ .check-icon {
background:url("../../assets/selected.png")no-repeat left center;
background-size:.42rem .42rem ;
}
2.模擬單選按鈕
相似效果
html代碼
<dl id="" class="money"> <dt>選擇補償金額<span class="p_help help">補償金說明</span></dt> <dd> <span> <input id="money_type_0" name="money_type" class="selection-rd hidden" type="radio" value="1" checked=""> <label class="selection-lb" for="money_type_0">10元</label> </span> <span> <input id="money_type_1" name="money_type" class="selection-rd hidden" type="radio" value="2"> <label class="selection-lb" for="money_type_1">20元</label> </span> <span> <input id="money_type_2" name="money_type" class="selection-rd hidden" type="radio" value="3"> <label class="selection-lb" for="money_type_2">50元</label> </span> </dd> </dl>
css代碼
.selection-rd:checked ~ .selection-lb { color: #e44; border:1px solid #e44; } .selection-lb { display: inline-block; margin:33px 30px 30px 0; width:150px; height: 64px; line-height: 64px; white-space: nowrap; background-color: #fff; border:1px solid #bbc; border-radius: 5px; text-align: center; font-size: 32px; }
jq代碼
var payLevel=$("input[name='money_type']:checked").val();
3.中間文字,兩邊橫線居中
效果
代碼
<div class="title-center"><div>學生信息</div></div>
/*中間文字兩邊橫線效果*/
.title-center {
position:relative;
width:100%;
text-align: center;
height: 100px;
line-height: 100px;
font-size: 28px;
color: #4d72e2;
}
.title-center div{
display: inline-block;
padding:0 20px;
}
.title-center:before ,.title-center:after{
display: inline-block;
position: relative;
content:"";
height:2px;
width:48px;
top:-6px;
background-color:#4d72e2;
}
當設置rem爲單位時,1px,會顯示偏大,將.title-center:before ,.title-center:after修改成以下:
.title-center:before, .title-center:after {
display: inline-block;
position: relative;
content: "";
height: 1px;
width: 1.88rem;
top: -.1rem;
background-color: #fd734f;
-webkit-transform: scaleY(0.5);
transform: scaleY(0.5);
-webkit-transform-origin: 0 0;
transform-origin: 0 0;
}
終極版,rem單位,橫線自適應長度!!!!
<div class="flexbox flexbox-middle">
<span class="flexchild border-center"></span>
<span style="padding:0 .2rem;">我要居中,兩邊橫線對齊</span>
<span class="flexchild border-center"></span>
</div>
.border-center{
/*display:inline-block; 使用flexchild佈局的時候,不能給元素設置這個屬性,否則, -webkit-box-flex: 1;會失效*/
height: 1px;
background-color: #fd734f;
-webkit-transform: scaleY(0.5);
transform: scaleY(0.5);
-webkit-transform-origin: 0 0;
transform-origin: 0 0;
}
中間文字,兩邊橫線居中方法2
效果圖
<div class="card-title"><span class="text">不辜負你比較快糖果盒若是好</span></div>
css
.card-title {
padding-top: .4rem;
font-size: .34rem;
color: #3c3c3c;
text-align: center;
font-weight: bold;
}
.card-title .text {
position: relative;
}
.card-title .text:before ,.card-title .text:after {
content: "";
display: inline-block;
position: absolute;
width: .4rem;
height: .32rem;
background: url('../images/card-title.png')no-repeat;
background-size: 100% 100%;
top: 50%;
margin-top: -.16rem;
}
.card-title .text:before{
left: -.51rem;
}
.card-title .text:after{
transform: rotateY(180deg);
-webkit-transform: rotateY(180deg);
right: -.51rem;
}
4.怎麼實現圖標水平垂直居中(rem單位)
利用background-size來設置背景圖的自己大小尺寸,而後利用background-position:center center;來設置背景圖相對元素的水平垂直居中,其中元素的寬是背景圖的寬,高就是原來的高
sass的寫法 @mixin headerIcon($width,$height,$url,$position) { position: absolute; $position: .3rem; top: 0; width: $width; //圖標的寬度 height: .88rem; //頭部的高度 background: url($url) no-repeat; background-position:left center; background-size:$width $height; font-size: .3rem; text-align: left; }
方法二,
html: <a> <i class="foot-nav1 icon"></i> <span>首頁</span> </a> css: a{display:inline-block;} .foot-nav1{ width: .66rem; height: .66rem; display: block; margin: 0 auto; background:url(); } span { display: block; line-height: .24rem; text-align: center; font-size: .24rem; height: .24rem; margin-bottom: .8rem; color: #666; }
5.頭部經常使用樣式設置
<div class="header flexbox flexbox-middle bg-white"><a class="left-icon"></a><h1>我是標題</h1><a class="right-icon"></a></div>
.header{ width: 100%; height: .88rem; position: absolute; left: 0; top: 0; z-index: 998; border-bottom: 1px solid #f1f1f1; text-align: center; h1{ font-size: .36rem; font-family: PingFangSC-Medium, sans-serif; } .left-icon{ position: absolute; width: .88rem; height: .88rem; left: .3rem; top: 0; background: url('../../assets/back-icon.png') no-repeat; background-size:.17rem .35rem; background-position: left center; } .right-icon{ position: absolute; width: .88rem; height: .88rem; right: .3rem; top: 0; background: url('../../assets/back-icon.png') no-repeat; background-size:.17rem .35rem; background-position: left center; }
6.經常使用表單佈局
效果:
代碼:
<div class="section2"> <div class="des-title"><span class="text">請認真填寫如下信息</span></div> <ul> <li class="flexbox"> <input type="text" placeholder="請輸入您的姓名" class="flexchild fill-content" id="tbName2"> </li> <li class="flexbox flexbox-middle"> <span class="fill-label">收貨地址:</span> <span class="adress" style="overflow: hidden;"> <input id="provinceCity2" name="rec_address_select" class="txt" placeholder="請選擇" readonly="readonly"> <input id="detailssq2" type="hidden" readonly="readonly"> <i class="ui-icon Rmore-icon noborder"></i> </span> </li> <li class="flexbox"> <input type="text" placeholder="請填寫詳細地址" class="flexchild fill-content " id="adressDetail"> </li> </ul> </div>
css:
.section2 li {
list-style: none;
position: relative;
width: 500px;
margin: 0 auto;
border: 1px solid #ffd6b9;
box-sizing: border-box;
padding: 17px 30px;
background-color: #fff;
margin-top: 20px;
border-radius: 40px;
}
.section2 li input {
background-color: transparent;
border: 0 none;
color: #333;
outline: none;
position: relative;
font-size: 26px;
width: 435px;
z-index: 102;
}
html:
<li class="flexbox"> <label>您的心上人:</label> <input type="text" placeholder="請輸入心上人姓名" class="flexchild" id="loveName"> </li>
css:
.sec3 li { position: relative; height: .88rem; -webkit-box-align: end; -moz-box-align: end; -ms-flex-align: end; -webkit-align-items: flex-end; align-items: flex-end; box-sizing: border-box; } .sec3 li label { padding-bottom: .2rem; } .sec3 li input { position: relative; width: 4.86rem; background: transparent; border: 0 none; border-bottom: 1px solid #dc115b; padding-bottom: .2rem; color: #efc283; font-size: .28rem; border-radius: 0; }
七、上方圖片下方文文字,水平居中佈局
效果
css樣式
.mall .details-foot .details-kefu { width: 1.56rem; height: .99rem; border-right: 1px solid #f1f1f1; }
.mall .details-foot .details-kefu i { display: block; width: .42rem; height: .42rem; margin: .12rem auto .06rem; background: url(data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAACoAAAAqCAYAAADFw8lbAAAAGXRFW…7oxfKRixjo4VSJhW/sUYi1M9kR4RNoUZHpQEuX+Z/pXwEGAHRzn0c9HGr7AAAAAElFTkSuQmCC) no-repeat; background-size: 100% 100%; }
.mall .details-foot .details-kefu-name { text-align: center; }
八、答題進度條
就是用來展現答題進度的進度條,效果以下
其中img是形狀底色(小圓圈是透明的)。而recommend-jd-bg是進度條背景色,recommend-jd-ks是控制進度的顏色!!,其中img的z-index>recommend-jd-bg>recommend-jd-ks
html:
<div class="recommend-jd">
<div class="recommend-jd-bg"></div>
<div class="recommend-jd-ks" style="width: 37.5%;"></div>
<img src="/src/m7.0/images/recommend/jd.png">
</div>
css:
.recommend-jd { width: 6.43rem; position: absolute; top: 1.59rem; left: .54rem; } .recommend-jd-bg { width: 100%; height: .31rem; background: #fff; position: absolute; top: 0; z-index: 97; } .recommend-jd-ks { width: 12.5%; //這個是js控制,根據題數的進度來控制! height: .31rem; background: #4a90ff; position: absolute; top: 0; z-index: 98; } .recommend-jd img { width: 100%; display: block; position: absolute; top: 0; z-index: 99; height: .31rem; }
進度條2
<div class="progressBar">
<span class="progressPer" style="width: 2rem;">
<span class="moneyBox">
<span class="moneyText">¥0.01</span>
</span>
</span>
</div>
.progressBar { margin: .3rem auto .1rem; width: 6.3rem; height: .1rem; background-color: rgb(72, 11, 29); } .progressPer { position: relative; top: 0; left: 0; display: inline-block; width: 0; height: .1rem; background-color: #efc283; } .moneyBox { position: absolute; right: -.53rem; top: .3rem; display: inline-block; width: 1.06rem; height: .4rem; background: url(../images/moneyBox.png)no-repeat; background-size: 100% 100%; } .moneyBox .moneyText { position: absolute; bottom: 0; left: 0; width: 1.04rem; height: .34rem; line-height: .34rem; text-align: center; color: #efc283; font-size: .26rem; }
9.答題測試1-10題都在同一個頁面
十、去掉selected自帶的下拉框標識,增長以下屬性
select { background: transparent; border: 0 none; outline:none; appearance:none; -moz-appearance:none; -webkit-appearance:none; }
十一、修改input的placeholder樣式
.detail-page input::-webkit-input-placeholder { /* WebKit, Blink, Edge */ font-size: .26rem; color:#b2b2b2; opacity: 1; } .detail-page input:-moz-placeholder { /* Mozilla Firefox 4 to 18 */ font-size: .26rem; color:#b2b2b2; opacity: 1; } .detail-page input::-moz-placeholder { /* Mozilla Firefox 19+ */ font-size: .26rem; color:#b2b2b2; opacity: 1; } .detail-page input:-ms-input-placeholder { /* Internet Explorer 10-11 */ font-size: .26rem; color:#b2b2b2; opacity: 1; }
12.input中增長disabled會自帶灰色,修改顏色以下
input:disabled{ border:1px solid #DDD; background-color:#F5F5F5; color:#ACA899; }
1三、多行文字左右對齊:
p {
text-align: justify;
text-justify: inter-ideograph;
}
效果
1四、實現單行文字兩端對齊,例如要實現下列單行文字對齊
方法一,使用僞類:
html:
<div class="line"> <div class="public">姓名</div> <b>:</b> <b>林小</b> </div> <div class="line"> <div class="public">身份證</div> <b>:</b> <b>111111111111</b> </div> <div class="line"> <div class="public">手機號碼</div> <b>:</b> <b>141000000</b> </div>
css:
.line{
width:100%;
height:15px;
margin:5px;
}
.public{
width:80px;
height:100%;
display:inline-block;
text-align: justify;
vertical-align:top;
}
.public::after{
content:"";
display: inline-block;
width:100%;
overflow:hidden;
height:0;
}
方法二使用letter-spacing來解決:
html:
<span style="font-size:12px;"><dl class="hotsearch" style="width:300px;"> <dt>熱門搜索</dt> <dd><a href="#" target="_blank" ref="nav" class="w3">電視機</a></dd> <dd><a href="#" target="_blank" ref="nav" class="w4">性感漂亮</a></dd> <dd><a href="#" target="_blank" ref="nav" class="w3">高跟鞋</a></dd> <dd><a href="#" target="_blank" ref="nav" class="w2">手機</a></dd> <dd><a href="#" target="_blank" ref="nav" class="w2">對齊</a></dd> <dd><a href="#" target="_blank" ref="nav" class="w3">牛仔褲</a></dd> <dd><a href="#" target="_blank" ref="nav" class="w4">小家碧玉</a></dd> <dd><a href="#" target="_blank" ref="nav" class="w2">家居</a></dd> </dl></span>
css:
.hotsearch dd{
float: left;
line-height: 24px;
margin-right: 30px;
overflow: hidden;
text-align: center;
width: 4em; /*這個值是看最長能顯示幾個文字,如x,則爲x em*/
}
.hotsearch dd a{
display:block;
}
.w2{
letter-spacing:2em; /*若是須要y個字兩端對齊,則爲(x-y)/(y-1),這裏是(4-2)/(2-1)=2em */
margin-right:-2em; /*同上*/
}
.w3{
letter-spacing:0.5em; /*若是須要y個字兩端對齊,則爲(x-y)/(y-1),這裏是(4-3)/(3-1)=0.5em */
margin-right:-0.5em; /*同上*/
}
效果
1五、實現圖片加載過程高度自適應
應用情景:在頁面佈局過程當中,遇到輪播圖或者大張圖片,當圖片下面還有其它塊內容,在圖片加載過程當中,因爲高度是0,下面的元素會往上跑,圖片加載完。元素會往下跑,給用戶感受抖動。
解決方法:在圖片最外層設置一個div,給這個div設置以下樣式
.img-box { overflow: hidden; width: 100%; height: 0; padding-bottom: 52%; /*方法二*/ width:100%; /*高度相對父級寬度比例*/ height: 52%vw;
background:#eee; }
1六、實現文字超出省略...(須要設置寬度,當父級元素使用flex佈局時,須要在display:flex;這邊設置min-width:0;否則ellipsis會失效!!)
.ellipsis { overflow: hidden; text-overflow: ellipsis; white-space: nowrap; } .ellipsis-2l { display: -webkit-box; overflow: hidden; text-overflow: ellipsis; -webkit-box-orient: vertical; -webkit-line-clamp: 2; //第幾行 }
1七、豎向滾動條
效果,每次點都要與時間對齊,能夠把小圓點放在跟日期同一個div上,而後橫線作成整個記錄的背景圖
html:
<div class="list"> <div class="list-item"> <div class="list-item-time flexbox flexbox-middle"><span class="progres2-item"></span><span>今天</span></div> <div class="list-item-award yhj">2元優惠券,無門檻可用<a class="go">去使用></a></div> <div class="list-item-text">已簽到,得到1個白鴿幣</div> </div> <div class="list-item"> <div class="list-item-time flexbox flexbox-middle"><span class="progres2-item"></span><span>今天</span></div> <div class="list-item-award yhj">2元優惠券,無門檻可用<a class="list-btn">去使用></a></div> <div class="excode">請在愛奇藝APP兌換,兌換碼:testPw5079</div> <div class="list-item-text">已簽到,得到1個白鴿幣</div> </div> <div class="list-item"> <div class="list-item-time flexbox flexbox-middle"><span class="progres2-item"></span><span>2018-09-28</span></div> <div class="list-item-text">已簽到,得到1個白鴿幣</div> </div> <div class="list-item"> <div class="list-item-time flexbox flexbox-middle"><span class="progres2-item"></span><span>今天</span></div> <div class="list-item-award yhj">2元優惠券,無門檻可用<a class="list-btn">去使用></a></div> <div class="excode">請在愛奇藝APP兌換,兌換碼:testPw5079</div> <div class="list-item-text">已簽到,得到1個白鴿幣</div> </div> </div>
css:
.list { padding-top: .1rem; padding-bottom: .1rem; font-size: .3rem; color: #333; background-color: #fff; } .list-item { width: 100%; margin-left: .32rem; margin-top: -.15rem; padding-bottom: .4rem; background: url("../images/border.png") no-repeat .1rem .21rem; background-size: 1px 100%; }
.progres2-item {
display: inline-block;
margin-right: .25rem;
width: .21rem;
height: .21rem;
background-color: #4d72e2;
border-radius: 50%;
}
/*最後一個沒有直線也就是沒有背景,只有一個的時候也沒有*/ .list-item:last-of-type{ background:transparent; } .list-item-award,.list-item-text { margin-left: .5rem; } .list-item-award{ padding-left: .53rem; margin-bottom: .12rem; margin-top: .22rem; } .list-item-text { width: 100%; padding-left: .46rem; padding-bottom: .16rem; background: url("../images/sign-icon.png") no-repeat left .05rem; background-size: .32rem .25rem; font-size: .26rem; color: #808080; box-sizing: border-box; border-bottom: 1px solid #f4f4f4; } .list-item:last-of-type .list-item-text { border-bottom: 0 none; } .list-item .list-btn { padding-left: .1rem; text-decoration: underline; font-size: .28rem; color: #316cec; }
1八、文字底部橫線背景
<div class="login-title">讓小白鴿知道您不是機器人哦!</div> .login-title { position: relative; height: .39rem; margin-top: .4rem; font-size: .34rem; color: #fff; text-align: center; } .login-title:after { content: ""; position: absolute; width: 5.05rem; height: .21rem; background-color: #fe923f; z-index: -1; left: 0; right: 0; margin: 0 auto; bottom: 0; }
