我的问题是我不能让我的侧边栏和桌子垂直对齐。它们使身体具有更长的宽度并且不会并排站立。我试过给桌子一个样式的" float:left"但这仍然使网站扩大,并没有看起来那么好。 我正在使用Bootstrap,CSS HTML,并希望在这些限制内获得解决方案 请参阅图片以获得更好的理解

答案 0 :(得分:1)
从我在html中看到的内容来看,你过分热衷于使用类,例如用于在屏幕上组织数据的行和列。过度应用类将会困扰你各种各样的CSS错误,所以作为一个挑选我试图保持你应用于元素的类的数量相当低(但这只是我的意见)
看一下flexbox,它是使用花车的一种巧妙的替代品,更直观。
Flexbox布局(灵活盒子)模块(目前是W3C最后调用工作草案)旨在提供一种更有效的方式来布置,对齐和分配容器中的项目之间的空间,即使它们的大小未知和/或动态的(因此是“flex”)。
TLDR解决方案:
将flex添加到外部容器中:
.container-fluid {
display: flex;
}
在该容器中添加您想要的所有项目:
<div class="container-fluid">
<div class="item1"> ITEM 1 CONTENT </div>
<div class="item2"> ITEM 2 CONTENT </div>
</div>
完整解决方案:
