I want to achieve this design:
Note that both text are perfectly top aligned but I'm almost sure this is impossible to achieve in CSS in a scalable way (I mean not hardcoding pixels with position relative/top for example).
Using flex looked like a good way to achieve this but since this is text, the top alignment is correct but based on the text 'bounding box' but the letters '77' don't take up 100% height of that box, causing it …
Babel 正在替换this

After searching to center my div all I could get was margin: 0 auto; together with an assigned width, but still it not working.
My problem is simply centering a div. I have no idea why margin: 0 auto; isn't working.
Here is the layout of my CSS/html:
CSS
.countdown-box {
position: absolute;
width: 80px;
margin: 0 auto;
height: 130px;
/*left: 50%;*/
background: #008040;
border-radius: 4px;
z-index: 2;

我希望它像这样,除了我希望线性梯度一个接一个地加载,并在可能的情况下使它们看起来像草绘的。
我尝试查看此代码: 页面加载时背景颜色发生变化
它似乎沿着我正在尝试的方式前进,但是我不希望整个背景发生变化,我只想绘制网格。
我还认为我可能需要使用它来使其在页面加载后绘制: JavaScript在页面加载后执行
我应该为线性渐变分配ID并在Javascript函数中调用它们吗?
