我目前正在使用 bootstrap 构建一个响应式网站，但我遇到了一个问题，引用下面的代码，我无法让它们彼此“对齐”。
This rough sketch would be what I want my end result to turn out

<h3><a href="#" onclick="hide;" >1Cross-country cycling</a></h3>
<p>Cross-country cycling is defined by the terrain on which it is performed. XC courses and trails consist of a mix of rough forest paths and singletrack (also referred to as doubletrack depending on width), smooth fireroads, and even paved paths connecting other trails. Riding or racing is also only deemed cross-country if the technical complexity of the trails is easy or moderate. Trails difficult even to experienced riders are more often dubbed "all-mountain", "freeride", or "downhill".</p>

<h3><a href="#">2Mountain bike trials</a></h3>
<p>Trials riding is an extreme test of bicycle handling skills, over all kinds of obstacles, both natural and man-made. It now has a strong - though small - following worldwide, though it is still primarily a European sport. Skills taken from trials riding can be used practically on any bicycle for balance, for example controlled braking and track standing, or balancing on the bike without putting a foot down. Competition trial bikes are characterized by powerful brakes, wide handlebars, lightweight parts, single-speed low gearing, low tire pressures with a thick rear tire, distinctive frame geometry, and usually no seat.</p>

<div class="col-sm-6 col-md-4">
<h3><a href="#">3Enduro</a></h3>
<p>Enduro is a form of Mountain bike racing in which there is a number of timed downhill sections of trail, and a number of uphill transfer stages, which are not timed, but might have time limits to complete. It is a stage-race format where the winner is the rider who accumulates the lowest combined time from the various timed sections. Mountain bike enduro competitions typically take place over the course of 1 or 2 days, however, week-long enduro competitions do also exist.</p>

<div class="col-sm-6 col-md-4">
<h3><a href="#">4Freeride </a></h3>
<p>The term freeriding was originally coined by snowboarders, meaning riding without a set course, goals or rules on natural terrain. In mountain biking, it is riding trail with the most creative line possible that includes style, amplitude, control, and speed.</p>
</div>
<div class="col-sm-6 col-md-4">
<h3><a href="#">5Dirt jumping</a></h3>
<p>Dirt jumping is one of the names given to the practice of riding bikes over cement type jumps of dirt or soil and becoming airborne. The idea is that after riding over the 'take off' the rider will become momentarily airborne, and aim to land on the 'landing'.</p>
</div>
<div class="col-sm-6 col-md-4">
<h3><a href="#">6Downhill mountain biking (DH)</a></h3>
<p>Downhill mountain biking (DH) is a genre of mountain biking practiced on steep, rough terrain that often features jumps, drops, rock gardens and other obstacles. Downhill bikes are heavier and stronger than other mountain bikes and feature front and rear suspension with over 8 inches (200mm) or (20cm) of travel, to glide quickly over rocks and tree roots.

最佳答案
卫平 你好。
您可能会发现每行添加 2 个项目会更好。
当 div 被压缩时，您将遇到对文本使用固定高度的问题。
