删除左右两侧的页脚空白

Question

我正在尝试删除页脚右侧和左侧的空白，当我输入代码“max-width: 1200px; margin: auto;”时它会继续出现使内容居中。我还有什么其他方法可以使内容居中并同时消除两边的白色间隙？

我尝试使用 margin-top、margin-left、margin-right、bootstrap 的 pull-left 和 pull-right、margin 和 padding 设置为 0、width:100% 等。没有任何效果。

谢谢。

我的代码是这样的：

body {
    margin-left: 0;
    padding: 0;
}

footer{
    position: relative;
    bottom: 0;
    max-width: 1200px;
  margin: auto;
    overflow-x: hidden;
}
.footer-distributed{
    background-color: #2c2c2c;
    box-shadow: 0 1px 1px 0 rgba(0, 0, 0, 0.12);
    width: 100%;
    text-align: left;
    font: normal 16px 'Varela Round';
    padding: 20px 50px;
    margin-top: 10px;
}

使用flexbox。页脚中的所有元素将自动在父元素中居中。

footer {
  background-color: #2c2c2c;
  position: relative;
  bottom: 0;
  left: 0;
  width: 100vw;
  display: flex;
  align-items: center;
  justify-content: center;
}

.footer-distributed {
  padding: 1em;
  display: flex;
  align-items: flex-start;
  justify-content: center;
  max-width: 1200px;
  width: 100%;
}
