我在侧边栏内对齐图标时遇到问题。我希望在侧边栏的右下角有一些社交图标。我尝试使用边距，但它看起来很可怕和丑陋。
Here's an example in JSBin（请将窗口调整为至少1000px。）
html, body, .container-fluid, .row {
height: 100%;
}
body {
background-color: #F2F0F1;
}
.sidebar {
background-color: tomato;
}
@media (min-width: 992px) {
.sidebar {
position: fixed;
top: 0;
left: 0;
bottom: 0;
z-index: 1000;
display: block;
background-color: tomato;
box-shadow: 0 0 25px rgba(0, 0, 0, 0.5);
}
}
ul li {
margin: 0 auto;
line-height: 50px;
list-style: none;
text-align: right;
margin-right: 20px;
}
ul li a {
color: rgba(255, 255, 255, 0.5);
text-decoration: none;
}
a:hover {
text-decoration: none;
background-color: rgba(0, 0, 0, 0.4);
padding: 4px;
color: tomato;
}
.hi {
margin-right: 20px;
text-align: right;
color: rgba(0, 0, 0, 0.4);
}
.content {
padding: 2% 4% 2% 4%;
color: rgba(0, 0, 0, 0.4);
background-color: #F2F0F1;
}
#fixedbutton {
position: fixed;
top: 0px;
right: 0px;
}
.sidebar-bottom-wrap {
position: absolute;
bottom: 60px;
right: 40px;
max-width: 200px;
}
.icons-sidebar-unit {
display: inline-block;
width: 30px;
height: 30px;
line-height: 30px;
vertical-align: baseline;<!DOCTYPE html>

最简单的方法可能是绝对定位.social-icons-sidebar { position: absolute; bottom: 0; right: 0; } https://jsbin.com/petixugodu/1/edit?html,css,output
您也可以使用flexbox。将侧边栏设置为列灵活容器，将页脚设置为flex-grow: 1，使其延伸到侧边栏的底部，使用margin-top: auto和order: 1将社交图标放在底部，然后对齐他们在text-align: right或align-self: flex-end https://jsbin.com/tukiqonase/edit?html,css,output

要将图标对齐，请尝试：
.icons-sidebar-unit {
float: right;
}
另外，在查看代码时，我发现你的图标单元的高度/宽度设置为30px。如果这是为了增加图标本身的大小，请尝试：
.icons-sidebar-unit {
font-size: 30px;
}
