html - 标签没有在 div 的左侧排列

Question

我有几个单选按钮，它们被带有背景图像的标签隐藏和覆盖。我的问题是标签没有在 div 的左侧对齐，而是在靠近中间的某个地方排列。几个小时以来，我一直在努力解决这个问题，但无法弄清楚。我的网站可以在这里看到:http://envisionhomedesign.com/derek/test12/index.html

CSS:

.button {
visibility:hidden;
clip:rect(0 0 0 0);
position: absolute;
}
label {
background-image: url("Images/Blue Button.png");
background-size: 130px;
background-repeat: no-repeat;
width: 130px;
height: 30px;
display: block;
float: left;
margin-right: 50px;
text-align:center;
font-size:small;
font-weight: 700;
padding-top:7px;
font-family: 'Lucida Sans Unicode, Lucida Grade, sans-serif';
}

.button:checked + label {
background-image: url("Images/Clicked Button.png");}
 input[type=button] { 
font-family: 'ubuntu', sans-serif;
width: 130px; 
height:30px;
background:transparent;
float:none;}

Answer 1

大多数浏览器都会向 ul 元素添加一些填充和边距。这种样式会导致您在左栏中的内容移动并溢出。您可以显式设置此填充/边距以覆盖浏览器细节。

ul { padding:0; margin:0; }
