你好,世界!
这是一个简单的营销或信息网站的模板。它包括一个称为jumbotron的大型标注和三个支持内容。把它作为一个起点来创造更独特的东西
window.jQuery | | document.write(“”)
我刚刚意识到我需要移除填充顶部:50px代码>从正文
就是这样。如果您从引导程序网站上查看,您会看到它下载了一个名为jumbotron.css的特定文件,以应用您拥有的确切样式。其内容:
/* Move down content because we have a fixed navbar that is 50px tall */
body {
padding-top: 50px;
padding-bottom: 20px;
}
