多选框（checkbox）用于选择列表中的一个或多个选项，而单选框（radio）用于从多个选项中只选择一个。


设置了 disabled 属性的单选或多选框都能被赋予合适的样式。对于和多选或单选框联合使用的 <label> 标签，如果也希望将悬停于上方的鼠标设置为“禁止点击”的样式，请将 .disabled 类赋予 .radio、.radio-inline、.checkbox、.checkbox-inline 或 <fieldset>。

内联单选和多选框

通过将 .checkbox-inline 或 .radio-inline 类应用到一系列的多选框（checkbox）或单选框（radio）控件上，可以使这些控件排列在一行。
