有人为我制作了这段代码,我认为其中有一些不必要的内容.
这是代码:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html
xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en"> <head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"
/> <title>IS THIS THING ON?</title> <link rel="stylesheet"
href="./wp-content/themes/cosmicbuddy/_inc/css/screen.css"
type="text/css" />
</style>
</head> <body>
<a href="<?php bp_send_public_message_link() ?>" class="myButton"><!--
button --></a>
</body> </html>
这也是它引用的CSS文件:
.myButton {
background: url(/wp-content/themes/cosmicbuddy/_inc/images/see.gif) no-repeat;
border: 1;
cursor: pointer;
display: block;
height: 22px;
width: 22px;
margin-left: 5px;
} .myButton:hover {
background: url(/wp-content/themes/cosmicbuddy/_inc/images/too.gif) no-repeat;
}
现在我有两个问题:
>第一段代码可以缩短吗?
>如何创建一个CSS文件,对多个这些设置实现设置.就像这个在我的CSS文件中链接:
06002
解决方法:
1 Can the first piece of code shortened?
如果您对尺寸如此关注,请删除<! - button - > HTML评论.
./wp-content/themes/cosmicbuddy/_inc/css/screen.css
是等于:
wp-content/themes/cosmicbuddy/_inc/css/screen.css
保存2个字符:)
在我看来,在CSS文件中,您可以缩短图像的路径.代替:
background: url(/wp-content/themes/cosmicbuddy/_inc/images/see.gif) no-repeat;
...
background: url(/wp-content/themes/cosmicbuddy/_inc/images/too.gif) no-repeat;
使用相对URL:
background: url(../images/see.gif) no-repeat;
...
background: url(../images/too.gif) no-repeat;
2 How can I create a CSS file that implements settings to more than one of these settings. Just like this one does in my CSS file to links:
如果您不想将CSS类添加到每个元素,则必须将它们包装在其他元素中
...
</head> <body>
<div class="buttons">
<a href="<?php bp_send_public_message_link() ?>" ></a>
<div class="buttons"><a href="<?php bp_send_public_message_link() ?>" ></a>
<div class="buttons"><a href="<?php bp_send_public_message_link() ?>" ></a>
<div class="buttons"><a href="<?php bp_send_public_message_link() ?>" ></a>
</div>
</body> </html>
和CSS
.buttons a {
background: url(../images/see.gif) no-repeat;
border: 1;
cursor: pointer;
display: block;
height: 22px;
width: 22px;
margin-left: 5px;
}
.buttons a:hover {
background: url(../images/too.gif) no-repeat;
}
如果未设置href属性,则通常使用光标.
