這個可以通過絕對定位，配合left設(shè)置 或者translate去實(shí)現(xiàn)
網(wǎng)站建設(shè)哪家好，找成都創(chuàng)新互聯(lián)公司！專注于網(wǎng)頁設(shè)計(jì)、網(wǎng)站建設(shè)、微信開發(fā)、小程序設(shè)計(jì)、集團(tuán)企業(yè)網(wǎng)站建設(shè)等服務(wù)項(xiàng)目。為回饋新老客戶創(chuàng)新互聯(lián)還提供了白塔免費(fèi)建站歡迎大家使用！
left的方法：
比如讓class為menu的元素寬為300px，高100%的，設(shè)置left為-300px；在這期間可以加一個過渡transition:left 0.3s ...；
然后讓class為menu active的元素設(shè)置 left設(shè)置為0就可以了 ，在這期間可以加一個過渡transition:left 0.3s ...；
然后可以通過Jquery的toggleClass('active');來實(shí)現(xiàn)切換
translate
比如讓class為menu的元素寬為300px，高100%的，設(shè)置left為-300px；在這期間可以加一個過渡transition:left 0.3s ...；
然后讓class為menu active的元素設(shè)置 transform:translate3d(-300px,0,0) ，在這期間可以加一個過渡transition:left 0.3s ...；
然后可以通過Jquery的toggleClass('active');來實(shí)現(xiàn)切換
這個過程中 需要注意 body需要overflow：hidden; (不然會有滾動條，可設(shè)置overflow-x即可)
left 和 translate 最好用translate ，translate3d可以開啟GPU硬件加速，性能會更好，體驗(yàn)會更流暢

1）、普通下拉列表菜單
html代碼如下：
form?action=""?method="get"?
label1、普通下拉列表菜單/label?
select?name=""?
option?value="0"DIVCSS5/option?
option?value="1"DIVCSS5/option?
/select?
/form?
2）、跳轉(zhuǎn)下拉列表菜單（如常見點(diǎn)擊后跳轉(zhuǎn)到選擇網(wǎng)站）
常常一些網(wǎng)站做友情鏈接，與部門之間使用select下拉標(biāo)簽實(shí)現(xiàn)網(wǎng)址跳轉(zhuǎn)。下面我們通過代碼與案例接受select跳轉(zhuǎn)菜單應(yīng)用。
跳轉(zhuǎn)菜單html代碼如下：
form?action=""?method="get"?
label2、跳轉(zhuǎn)的下拉列表菜單/label?
select?name="jumpMenu"?id="jumpMenu"
onchange="MM_jumpMenu('parent',this,0)"?
option?value=""Rothur/option?
option?value=""Rothur/option?
/select?
/form?
實(shí)現(xiàn)跳轉(zhuǎn)還需要在head標(biāo)簽內(nèi)加入Js腳本動作代碼：
script?type="text/javascript"?!--?function?MM_jumpMenu(targ,selObj,restore){?//v3.0?eval(targ+".location='"+selObj.options[selObj.selectedIndex].value+"'");?if?(restore)?selObj.selectedIndex=0;?}?//--?/script

一共有4種側(cè)滑動畫特效。這款CSS3菜單的特點(diǎn)是鼠標(biāo)劃過時即可以各種動畫方式展開和隱藏菜單項(xiàng)，該動畫方式由CSS3中的transition-delay屬性來完成
