CSS3 多媒體查詢實例
CSS3 多媒體查詢實例
本章節(jié)我們將為大家演示一些多媒體查詢實例。
開始之前我們先制作一個電子郵箱的鏈接列表。HTML 代碼如下：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<style>
ul {
list-style-type: none;
}
ul li a {
color: green;
text-decoration: none;
padding: 3px;
display: block;
}
</style>
</head>
<body>
<ul>
<li><a data-email="johndoe@example.com" href="">John Doe</a></li>
<li><a data-email="marymoe@example.com" href="">Mary Moe</a></li>
<li><a data-email="amandapanda@example.com" href="">Amanda Panda</a></li>
</ul>
</body>
</html>注意 data-email 屬性。在 HTML 中我們可以使用帶 data- 前綴的屬性來存儲信息。
520 到 699px 寬度 - 添加郵箱圖標(biāo)
當(dāng)瀏覽器的寬度在 520 到 699px, 郵箱鏈接前添加郵件圖標(biāo)：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<style>
ul {
list-style-type: none;
}
ul li a {
color: green;
text-decoration: none;
padding: 3px;
display: block;
}
@media screen and (max-width: 699px) and (min-width: 520px) {
ul li a {
padding-left: 30px;
background: url(../style/images/email-icon.png) left center no-repeat;
}
}
</style>
</head>
<body>
<h1>重置瀏覽器窗口，查看效果!</h1>
<ul>
<li><a data-email="johndoe@example.com" href="">John Doe</a></li>
<li><a data-email="marymoe@example.com" href="">Mary Moe</a></li>
<li><a data-email="amandapanda@example.com" href="">Amanda Panda</a></li>
</ul>
</body>
</html>700 到 1000px - 添加文本前綴信息
當(dāng)瀏覽器的寬度在 700 到 1000px, 會在郵箱鏈接前添加 "Email: ":
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<style>
ul {
list-style-type: none;
}
ul li a {
color: green;
text-decoration: none;
padding: 3px;
display: block;
}
@media screen and (max-width: 699px) and (min-width: 520px) {
ul li a {
padding-left: 30px;
background: url(../style/images/email-icon.png) left center no-repeat;
}
}
@media screen and (max-width: 1000px) and (min-width: 700px) {
ul li a:before {
content: "Email: ";
font-style: italic;
color: #666666;
}
}
</style>
</head>
<body>
<h1>重置瀏覽器窗口，查看效果!</h1>
<ul>
<li><a data-email="johndoe@example.com" href="">John Doe</a></li>
<li><a data-email="marymoe@example.com" href="">Mary Moe</a></li>
<li><a data-email="amandapanda@example.com" href="">Amanda Panda</a></li>
</ul>
</body>
</html>大于 1001px 寬度 - 添加郵件地址
當(dāng)瀏覽器的寬度大于 1001px 時，會在鏈接后添加郵件地址接。
我們會使用 data- 屬性來為每個人名后添加郵件地址：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<style>
ul {
list-style-type: none;
}
ul li a {
color: green;
text-decoration: none;
padding: 3px;
display: block;
}
@media screen and (max-width: 699px) and (min-width: 520px) {
ul li a {
padding-left: 30px;
background: url(../style/images/email-icon.png) left center no-repeat;
}
}
@media screen and (max-width: 1000px) and (min-width: 700px) {
ul li a:before {
content: "Email: ";
font-style: italic;
color: #666666;
}
}
@media screen and (min-width: 1001px) {
ul li a:after {
content: " (" attr(data-email) ")";
font-size: 12px;
font-style: italic;
color: #666666;
}
}
</style>
</head>
<body>
<h1>重置瀏覽器窗口，查看效果!</h1>
<ul>
<li><a data-email="johndoe@example.com" href="">John Doe</a></li>
<li><a data-email="marymoe@example.com" href="">Mary Moe</a></li>
<li><a data-email="amandapanda@example.com" href="">Amanda Panda</a></li>
</ul>
</body>
</html>大于 1151px 寬度 - 添加圖標(biāo)
當(dāng)瀏覽器的寬度大于 1001px 時，會在人名前添加圖標(biāo)。
實例中，我們沒有編寫額外的查詢塊，我們可以在已有的查詢媒體后使用逗號分隔來添加其他媒體查詢 (類似 OR 操作符):
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<style>
ul {
list-style-type: none;
}
ul li a {
color: green;
text-decoration: none;
padding: 3px;
display: block;
}
@media screen and (max-width: 699px) and (min-width: 520px), (min-width: 1151px) {
ul li a {
padding-left: 30px;
background: url(../style/images/email-icon.png) left center no-repeat;
}
}
@media screen and (max-width: 1000px) and (min-width: 700px) {
ul li a:before {
content: "Email: ";
font-style: italic;
color: #666666;
}
}
@media screen and (min-width: 1001px) {
ul li a:after {
content: " (" attr(data-email) ")";
font-size: 12px;
font-style: italic;
color: #666666;
}
}
</style>
</head>
<body>
<h1>重置瀏覽器窗口，查看效果!</h1>
<ul>
<li><a data-email="johndoe@example.com" href="">John Doe</a></li>
<li><a data-email="marymoe@example.com" href="">Mary Moe</a></li>
<li><a data-email="amandapanda@example.com" href="">Amanda Panda</a></li>
</ul>
</body>
</html>
