ten*_*tio 2 html javascript css charts chart.js
我正在学习 JavaScript、CSS 和 Chart.JS。我得到了一些代码来进行逆向工程和学习。我的最终任务是将两个水平图 div向左加宽，而不与大垂直条形图重叠。
基本上，我只是希望我的两个小图的宽度向左扩展。Codepen在这里： https ://codepen.io/tenebris_silentio/pen/VwaGdaP

</html>考虑到网格显示的性质，您无法在不破坏布局的情况下真正将卡片扩展到左侧。所需要的是对grid-templatefor进行重新调整.dashboard-container。
其中存在边距和填充、fr网格模板属性中单位的误用以及媒体查询断点不一致的问题。
