Question

我正在创建一个控制机器人的html页面，我正试图让布局变得更好。

目前有一个实时视频输入，下面是一列8个按钮。这些按钮具有CSS属性，当它们被点击等时会改变它们的颜色。我只是希望能够移动按钮以将它们排列在网格或一组列中。

我该怎么做？我是否需要使用CSS来创建一些列，还是因为我将按钮定位而不是文本而更难？

我添加了浮动：左;到CSS和按钮现在是水平对齐的：

#controls button {
display: block;
margin: 20px 20px 20px 20px;
width: 60px;
height: 20px;
font-size: 8pt;
font-weight: bold;
color: white;
float:left;

我的应用程序与您的应用程序类似...边框周围有GPIO按钮的实时视频。我不是专家，只是分享我发现的东西。我希望这有帮助...
