我不明白为什么 css 类不起作用。
newcss.css:
.greenClass {
color: green;
}
索引.xhtml:
<?xml version='1.0' encoding='UTF-8' ?>
<!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"
xmlns:h="http://xmlns.jcp.org/jsf/html">
<h:head>
<h:outputStylesheet library="css" name="newcss.css"/>
</h:head>
<h:form styleClass="greenClass">
<h:outputLabel styleClass="greenClass" value="AAA"/>
</h:form>
</html>
HTML代码
<?xml version='1.0' encoding='UTF-8' ?>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"><head id="j_idt2"><link type="text/css" rel="stylesheet" href="/WA/faces/javax.faces.resource/newcss.css" /></head>
<form id="j_idt4" name="j_idt4" method="post" action="/WA/faces/index.xhtml" class="greenClass" enctype="application/x-www-form-urlencoded">
<input type="hidden" name="j_idt4" value="j_idt4" />
<label class="greenClass">AAA</label><input type="hidden" name="javax.faces.ViewState" id="j_id1:javax.faces.ViewState:0" value="-7146797988252848648:-7580080555543519594" autocomplete="off" />
</form>
</html>
这行不通
<?xml version='1.0' encoding='UTF-8' ?>
<!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"
xmlns:h="http://xmlns.jcp.org/jsf/html">
<h:form>
<h:outputLabel styleClass="greenClass" value="AAA"/>
</h:form>
</html>
但以下工作正常:
<?xml version='1.0' encoding='UTF-8' ?>
<!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"
xmlns:h="http://xmlns.jcp.org/jsf/html">
<h:form>
<h:outputLabel style="color: green" value="AAA"/>
</h:form>
</html>
HTML代码:
<?xml version='1.0' encoding='UTF-8' ?>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<form id="j_idt2" name="j_idt2" method="post" action="/WA/faces/index.xhtml" enctype="application/x-www-form-urlencoded">
<input type="hidden" name="j_idt2" value="j_idt2" />
<label style="color:green">AAA</label><input type="hidden" name="javax.faces.ViewState" id="j_id1:javax.faces.ViewState:0" value="8578298320156968921:4997153480898762925" autocomplete="off" />
</form>
</html>
你能解释一下这可能是什么原因以及如何解决这个问题吗？
最佳答案
在你的例子中，这是行不通的，你错过了
<h:head>
<h:outputStylesheet library="css" name="newcss.css"/>
</h:head>
部分。
关于css 不适用于 html 组件，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/20302306/
