如何使按钮水平对齐？
我当前的设计CSS出现问题。我几乎完成了所有工作。但是，在最终产品中，我注意到“查看参与按钮”未与其他“查看参与按钮”对齐。他们似乎上下波动。都应该对齐。我调整了周围的桌子/盒子，以便通过将高度固定为150px来对齐它们。谁能看到我的代码中的错误并指出如何修复这一部分？我下面有一张图片，看起来像什么：

如果需要，我也可以添加CSS样式，但是我认为我拥有的内联CSS需要进行调整/修改/添加。
1 个答案:
答案 0 :(得分：1)
我从完全放弃基于表的布局开始，这简化了HTML。然后，我取消了内联样式，这进一步简化了事情。
所以我们有一个事物列表，顺序无关紧要，所以让我们使用无序列表（ul）。
关于如何布置列表元素，您有很多选择，为简单起见，我选择了display:block。您还可以查看Flex，CSS Grid甚至是CSS Tables。
要使按钮与底部对齐，我创建了一个具有固定高度的元素，并将其设置为position:relative。然后，我将position:absolute应用于按钮元素并设置相对于父元素底部的位置。
