我想要使用HTML5和CSS3來加載MP3/OGG,它將與正在顯示的文本一起閱讀。當它完成屏幕上的內容時,它切換到新的屏幕。使用HTML5和CSS3來切換'幀'這麼多秒,如閃存
因此,第一個屏幕會在MP3開始時加載,並保持到12秒(這是MP3需要多長時間才能讀取它)。在12秒後,它切換到下一個文本,這將保持到22秒。總共有7段。
下面是一些編碼,我發現一個例子,但我不能編輯它與我需要的時間正常工作。在HTML的
基礎:
<audio controls="controls" preload="auto" autoplay="autoplay">
<source src="valmp3.ogg" type="audio/ogg" />
<source src="valmp3.mp3" type="audio/mpeg" />
Your browser does not support the audio element.
</audio>
<ul>
<li>Paragraph 1</li>
<!--^^Should load when the mp3 starts and stay for 12 seconds^^-->
<li>Paragraph 2</li>
<!--^^Should load at 12 seconds and stay until 22 seconds^^-->
<li> Paragraph 3</li>
<li> Paragraph 4</li>
<li>Paragraph 5</li>
<li>Paragraph 6</li>
<li>Paragraph 7</li>
</ul>
的CSS:
* {
margin: 0;
padding: 0;
}
body{
background: #422A20;
font-size: 2em;
}
ul {
height: 100%;
left: 0;
position: fixed;
top: 0;
width: 100%;
z-index: 0;
}
ul li {
color: transparent;
font-size: 250%;
position: absolute;
text-align: center;
top: 35%;
width: 100%;
}
/* delay between each text */
ul li:nth-child(1),
ul li:nth-child(2),
ul li:nth-child(3),
ul li:nth-child(4) {
-moz-animation: blurFadeInOut 3s ease-in backwards;
-ms-animation: blurFadeInOut 3s ease-in backwards;
-webkit-animation: blurFadeInOut 3s ease-in backwards;
}
ul li:nth-child(1) {
-webkit-animation-delay: 0s;
-moz-animation-delay: 0s;
-ms-animation-delay: 0s;
animation-delay: 0s;
}
ul li:nth-child(2) {
-webkit-animation-delay: 3s;
-moz-animation-delay: 3s;
-ms-animation-delay: 3s;
animation-delay: 3s;
}
ul li:nth-child(3) {
-webkit-animation-delay: 6s;
-moz-animation-delay: 6s;
-ms-animation-delay: 6s;
animation-delay: 6s;
}
ul li:nth-child(4) {
-webkit-animation-delay: 9s;
-moz-animation-delay: 9s;
-ms-animation-delay: 9s;
animation-delay: 9s;
}
ul li:nth-child(5) {
-webkit-animation-delay: 12s;
-moz-animation-delay: 12s;
-ms-animation-delay: 12s;
animation-delay: 12s;
}
/* delay for the last slide */
ul li:nth-child(5) span {
-webkit-animation: blurFadeIn 3s ease-in 12s backwards;
-moz-animation: blurFadeIn 1s ease-in 12s backwards;
-ms-animation: blurFadeIn 3s ease-in 12s backwards;
animation: blurFadeIn 3s ease-in 12s backwards;
color: transparent;
text-shadow: 0px 0px 1px #fff;
}
ul li:nth-child(5) span:nth-child(2) {
-webkit-animation-delay: 13s;
-moz-animation-delay: 13s;
-ms-animation-delay: 13s;
animation-delay: 13s;
}
ul li:nth-child(5) span:nth-child(3) {
-webkit-animation-delay: 14s;
-moz-animation-delay: 14s;
-ms-animation-delay: 14s;
animation-delay: 14s;
}
代碼爲動畫:
@-moz-keyframes blurFadeInOut {
0% { opacity: 0; text-shadow: 0px 0px 40px #fff; -moz-transform: scale(1.3); }
25%, 75% { opacity: 1; text-shadow: 0px 0px 1px #fff; -moz-transform: scale(1); }
100% { opacity: 0; text-shadow: 0px 0px 50px #fff; -moz-transform: scale(0); }
}
@-webkit-keyframes blurFadeInOut {
0% { opacity: 0; text-shadow: 0px 0px 40px #fff; -webkit-transform: scale(1.3); }
25%, 75% { opacity: 1; text-shadow: 0px 0px 1px #fff; -webkit-transform: scale(1); }
100% { opacity: 0; text-shadow: 0px 0px 50px #fff; -webkit-transform: scale(0); }
}
@keyframes blurFadeInOut {
0% { opacity: 0; text-shadow: 0px 0px 40px #fff; transform: scale(1.3); }
25%, 75% { opacity: 1; text-shadow: 0px 0px 1px #fff; transform: scale(1); }
100% { opacity: 0; text-shadow: 0px 0px 50px #fff; transform: scale(0); }
}
你會需要一些JavaScript時,該文件已被加載到啓動動畫,使您的時間將匹配檢測。 – Shmiddty
是的,我仍然試圖弄清楚。以上是我目前的編碼,在解決動畫問題後,我會嘗試獲取JavaScript加載。到目前爲止,我只是在我的電腦上測試它,所以加載時間是即時的。 –
我們可能需要查看'blurFadeInOut'的定義。 – Shmiddty
