标签： html5 twitter-bootstrap css3 responsive-design

我无法在引导程序页面（居中的列）上以直线对齐<h2>，如下面的代码段所示。

h1 {
	text-align: center;
}

.navbar-default {
	background-color: #F5F5F5;
    border-color: #E7E7E7;
    opacity: 100%;
}

.row-footer{
    background-color: #AfAfAf;
    margin:0px auto;
    padding: 20px 0px 20px 0px;
}

.icons {
	display: inline;
}

/* centered columns styles */
.row-centered {
    text-align:center;
}
.col-centered {
    display:inline-block;
    float:none;
    /* reset the text-align */
    text-align:left;
    /* inline-block space fix */
    margin-right:-4px;
}

如果我在<ul>之后添加<h2>，则剩余的<h2>未对齐。 I have shown the picture here如何对齐它们？

由于您尝试为小屏幕连续添加三列，因此它已中断。 为列添加适当的类。 col-xs-12 col-lg-4 col-centered 

  
h1 {
  text-align: center;
}

.navbar-default {
  background-color: #F5F5F5;
    border-color: #E7E7E7;
    opacity: 100%;
}

.row-footer{
    background-color: #AfAfAf;
    margin:0px auto;
    padding: 20px 0px 20px 0px;
}

.icons {
  display: inline;
}

/* centered columns styles */
.row-centered {
    text-align:center;
}
.col-centered {
    display:inline-block;
    float:none !important;
    /* reset the text-align */
    text-align:left;
    /* inline-block space fix */
