溢出隐藏，不起作用

Question

我是html＆amp;的新手css和我正在练习免费模板，但现在我遇到了问题。我的页眉和页脚右侧有空白区域，底部有一个不会消失的滚动条。 有人可以帮我解决这个问题。

Answer 1

您的代码存在的问题是您使用了px表示宽度，高度，左，右间距等。请尝试使用%，以便它们在不同的屏幕尺寸上不会以不同的方式显示

另外，我建议您使用bootstrap这样的框架来构建您的网页，而不是输入整个CSS。

我认为这可以解决您留下间距/滚动问题的问题：

@font-face {
  font-family: 'Arimo-Bold';
  src: url('fonts/Arimo-Bold/Arimo-Bold.eot');
  src: url('fonts/Arimo-Bold/Arimo-Bold.woff') format('woff'), url('fonts/Arimo-Bold/Arimo-Bold.ttf') format('truetype'), url('fonts/Arimo-   Bold/Arimo-Bold.svg') format('svg');
}
@font-face {
  font-family: 'ChangaOne';
  src: url('fonts/ChangaOne/ChangaOne-Regular.eot');
  src: url('fonts/ChangaOne/ChangaOne-Regular.woff') format('woff'), url('../fonts/ChangaOne/ChangaOne-Regular.ttf') format('truetype'), url('../fonts/ChangaOne/ChangaOne-Regular.svg') format('svg');
}
@font-face {
