在我們這次的新設(shè)計(jì)教程中，我將向您展示如何創(chuàng)建純css3的loading加載動(dòng)畫(huà)組件(沒(méi)有任何圖像)。我認(rèn)為它可以為你減少項(xiàng)目的代碼量和額外的圖像對(duì)你網(wǎng)站的負(fù)載。我準(zhǔn)備了三種不同風(fēng)格的加載組件。現(xiàn)在，讓我們看看我做的。
css3-loading
step 1. html
你可以在這里看到的三個(gè)元素–放置“加載”元素的div。
<div class=main_body>
<div class=element>
<div class=loading1>
<div></div>
<div></div>
<div></div>
<div></div>
<div></div>
<div></div>
<div></div>
<div></div>
</div>
</div>
<div class=element>
<div class=loading2>
<div></div>
<div></div>
<div></div>
<div></div>
<div></div>
<div></div>
<div></div>
<div></div>
</div>
</div>
<div class=element>
<div class=loading3>
<div></div>
<div></div>
<div></div>
<div></div>
<div></div>
</div>
</div>
</div>
step 2. css
現(xiàn)在，最有趣的一步，我會(huì)給你風(fēng)格各加載的元素。歡迎來(lái)檢查的第一個(gè)樣式：
.loading1 {
height:100px;
position:relative;
width:80px;
}
.loading1 > div {
background-color:#ffffff;
height:30px;
position:absolute;
width:12px;
/* css3 radius */
-moz-border-radius:5px;
-webkit-border-radius:5px;
border-radius:5px;
/* css3 transform - scale */
-webkit-transform:scale(0.4);
-moz-transform:scale(0.4);
-o-transform:scale(0.4);
/* css3 animation */
-webkit-animation-name:loading1;
-webkit-animation-duration:1.04s;
-webkit-animation-iteration-count:infinite;
-webkit-animation-direction:linear;
-moz-animation-name:loading1;

-moz-animation-iteration-count:infinite;
-moz-animation-direction:linear;
-o-animation-name:loading1;
-o-animation-duration:1.04s;
-o-animation-iteration-count:infinite;
-o-animation-direction:linear;
}
.loading1 > div:nth-child(1) {
left:0;
top:36px;
/* css3 transform - rotate */
-webkit-transform:rotate(-90deg);
-moz-transform:rotate(-90deg);
-o-transform:rotate(-90deg);
/* css3 animation */
-webkit-animation-delay:0.39s;
-moz-animation-delay:0.39s;
-o-animation-delay:0.39s;
}
.loading1 > div:nth-child(2) {
left:10px;
top:13px;
/* css3 transform - rotate */
-webkit-transform:rotate(-45deg);
-moz-transform:rotate(-45deg);
-o-transform:rotate(-45deg);
/* css3 animation */
-webkit-animation-delay:0.52s;
-moz-animation-delay:0.52s;
-o-animation-delay:0.52s;
}
.loading1 > div:nth-child(3) {
left:34px;
top:4px;
/* css3 transform - rotate */
-webkit-transform:rotate(0deg);
-moz-transform:rotate(0deg);
-o-transform:rotate(0deg);
/* css3 animation */
-webkit-animation-delay:0.65s;
-moz-animation-delay:0.65s;
-o-animation-delay:0.65s;
}
.loading1 > div:nth-child(4) {
right:10px;
top:13px;
/* css3 transform - rotate */
-webkit-transform:rotate(45deg);
-moz-transform:rotate(45deg);
-o-transform:rotate(45deg);
/* css3 animation */
-webkit-animation-delay:0.78s;
-moz-animation-delay:0.78s;
-o-animation-delay:0.78s;
}
.loading1 > div:nth-child(5) {
right:0;
top:36px;
/* css3 transform - rotate */
-webkit-transform:rotate(90deg);
-moz-transform:rotate(90deg);
-o-transform:rotate(90deg);
/* css3 animation */
-webkit-animation-delay:0.91s;
-moz-animation-delay:0.91s;
-o-animation-delay:0.91s;
}
.loading1 > div:nth-child(6) {
right:10px;
bottom:9px;
/* css3 transform - rotate */
-webkit-transform:rotate(135deg);
-moz-transform:rotate(135deg);
-o-transform:rotate(135deg);
/* css3 animation */
-webkit-animation-delay:1.04s;
-moz-animation-delay:1.04s;
-o-animation-delay:1.04s;
}
.loading1 > div:nth-child(7) {
bottom:0;
left:34px;
/* css3 transform - rotate */
-webkit-transform:rotate(180deg);
-moz-transform:rotate(180deg);
-o-transform:rotate(180deg);
/* css3 animation */
-webkit-animation-delay:1.17s;
-moz-animation-delay:1.17s;
-o-animation-delay:1.17s;
}
.loading1 > div:nth-child(8) {
left:10px;
bottom:9px;
/* css3 transform - rotate */
-webkit-transform:rotate(-135deg);
-moz-transform:rotate(-135deg);
-o-transform:rotate(-135deg);
/* css3 animation */
-webkit-animation-delay:1.3s;
-moz-animation-delay:1.3s;
-o-animation-delay:1.3s;
}
/* css3 keyframes - loading1 */
@-webkit-keyframes loading1 {
0%{ background-color:#000000 }
100%{ background-color:#ffffff }
}
@-moz-keyframes loading1 {
0%{ background-color:#000000 }
100%{ background-color:#ffffff }
}
@-o-keyframes loading1 {
0%{ background-color:#000000 }
100%{ background-color:#ffffff }
}
你可以看到–我用css3動(dòng)畫(huà)關(guān)鍵幀，每一步(點(diǎn))是彼此分離的延遲?，F(xiàn)在，請(qǐng)查看我們的第二負(fù)載的風(fēng)格元素：
.loading2 {
height:140px;
position:relative;
width:140px;
/* css3 transform - scale */
-webkit-transform:scale(0.6);
-moz-transform:scale(0.6);
-o-transform:scale(0.6);
}
.loading2 > div {
background-color:#ffffff;
height:25px;
position:absolute;
width:25px;
/* css3 radius */
-moz-border-radius:15px;
-webkit-border-radius:15px;
border-radius:15px;
/* css3 animation */
-webkit-animation-name:loading2;
-webkit-animation-duration:1.04s;
-webkit-animation-iteration-count:infinite;
-webkit-animation-direction:linear;
-moz-animation-name:loading2;
-moz-animation-duration:1.04s;
-moz-animation-iteration-count:infinite;
-moz-animation-direction:linear;
-o-animation-name:loading2;
-o-animation-duration:1.04s;
-o-animation-iteration-count:infinite;
-o-animation-direction:linear;
}
.loading2 > div:nth-child(1) {
left:0;
top:57px;
/* css3 animation */
-webkit-animation-delay:0.39s;
-moz-animation-delay:0.39s;
-o-animation-delay:0.39s;
}
.loading2 > div:nth-child(2) {
left:17px;
top:17px;
/* css3 animation */
-webkit-animation-delay:0.52s;
-moz-animation-delay:0.52s;
-o-animation-delay:0.52s;
}
.loading2 > div:nth-child(3) {
left:57px;
top:0;
/* css3 animation */
-webkit-animation-delay:0.65s;
-moz-animation-delay:0.65s;
-o-animation-delay:0.65s;
}
.loading2 > div:nth-child(4) {
right:17px;
top:17px;
/* css3 animation */
-webkit-animation-delay:0.78s;
-moz-animation-delay:0.78s;
-o-animation-delay:0.78s;
}
.loading2 > div:nth-child(5) {
right:0;
top:57px;
/* css3 animation */
-webkit-animation-delay:0.91s;
-moz-animation-delay:0.91s;
-o-animation-delay:0.91s;
}
.loading2 > div:nth-child(6) {
right:17px;
bottom:17px;
/* css3 animation */
-webkit-animation-delay:1.04s;
-moz-animation-delay:1.04s;
-o-animation-delay:1.04s;
}
.loading2 > div:nth-child(7) {
left:57px;
bottom:0;
/* css3 animation */
-webkit-animation-delay:1.17s;
-moz-animation-delay:1.17s;
-o-animation-delay:1.17s;
}
.loading2 > div:nth-child(8) {
left:17px;
bottom:17px;
/* css3 animation */
-webkit-animation-delay:1.3s;
-moz-animation-delay:1.3s;
-o-animation-delay:1.3s;
}
/* css3 keyframes - loading2 */
@-webkit-keyframes loading2 {
0%{ background-color:#000000 }
100%{ background-color:#ffffff }
}
@-moz-keyframes loading2 {
0%{ background-color:#000000 }
100%{ background-color:#ffffff }
}
@-o-keyframes loading2 {
0%{ background-color:#000000 }
100%{ background-color:#ffffff }
}
我在這里使用相同的理念作為第一要素，但是，稍微改變風(fēng)格。最后–第三”加載元件：
.loading3 > div {
background-color:#ffffff;
border:1px solid #000000;
float:left;
height:114px;
margin-left:5px;
width:30px;
opacity:0.1;
/* css3 transform - scale */
-webkit-transform:scale(0.8);
-moz-transform:scale(0.8);
-o-transform:scale(0.8);
/* css3 animation */
-webkit-animation-name:loading3;
-webkit-animation-duration:1.2s;
-webkit-animation-iteration-count:infinite;
-webkit-animation-direction:linear;
-moz-animation-name:loading3;
-moz-animation-duration:1.2s;
-moz-animation-iteration-count:infinite;
-moz-animation-direction:linear;
-o-animation-name:loading3;
-o-animation-duration:1.2s;
-o-animation-iteration-count:infinite;
-o-animation-direction:linear;
}
.loading3 > div:nth-child(1) {
/* css3 animation */
-webkit-animation-delay:0.24s;
-moz-animation-delay:0.24s;
-o-animation-delay:0.24s;
}
.loading3 > div:nth-child(2) {
/* css3 animation */
-webkit-animation-delay:0.48s;
-moz-animation-delay:0.48s;
-o-animation-delay:0.48s;
}
.loading3 > div:nth-child(3) {
/* css3 animation */
-webkit-animation-delay:0.72s;
-moz-animation-delay:0.72s;
-o-animation-delay:0.72s;
}
.loading3 > div:nth-child(4) {
/* css3 animation */
-webkit-animation-delay:0.96s;
-moz-animation-delay:0.96s;
-o-animation-delay:0.96s;
}
.loading3 > div:nth-child(5) {
/* css3 animation */
-webkit-animation-delay:1.2s;
-moz-animation-delay:1.2s;
-o-animation-delay:1.2s;
}
/* css3 keyframes - loading3 */
@-webkit-keyframes loading3 {
0% {
-webkit-transform:scale(1.2);
opacity:1;
}
100% {
-webkit-transform:scale(0.7);
opacity:0.1;
}
}
@-moz-keyframes loading3 {
0% {
-moz-transform:scale(1.2);
opacity:1;
}
100% {
-moz-transform:scale(0.7);
opacity:0.1;
}
}
@-o-keyframes loading3 {
0% {
-o-transform:scale(1.2);
opacity:1;
}
100% {
-o-transform:scale(0.7);
opacity:0.1;
}
}
這就是今天的。我們剛剛創(chuàng)建的三種不同的“加載”元素。我希望一切都對(duì)你很容易和你一樣的結(jié)果。祝你好運(yùn)!
