Question

我是html代码的新手，因此我对html编码没有太多了解。当我使用内联样式时，它似乎工作正常，但head元素中的css代码不会显示在网页中。代码对我来说似乎很好。我已尝试在Chrome和Firefox中运行此代码，但问题仍然存在于两者中。请检查我的代码和＆amp;给我任何建议或解决方案。感谢。

fieldset: {
    			background: lightyellow;
    			border: 10px solid yellow;
    			margin-bottom: 10px;
    			width: 720px;
    		}
    		label: {
    			width: 180px;
    		}

Answer 1

从样式属性中删除此“冒号：”。

fieldset : {

然后其他人也会正常工作。

<!DOCTYPE html>
<html>
<head>
	<title>Dating Web Site</title>
	<style>
		fieldset {
			background: lightyellow;
			border: 10px solid yellow;
			margin-bottom: 10px;
			width: 720px;
		}
		label {
			width: 180px;
		}
	</style>
</head>
