css3垂直时间轴创意特效

这是一款非常有创意的CSS3垂直时间轴设计效果。该垂直时间轴采用响应式设计，通过不同的颜色来区分时间点。

使用方法

HTML结构

该CSS3垂直时间轴的基本HTML结构如下：

<div class="container">
    <div class="row">
      <div class="col-md-12">
          <div class="main-timeline">
              <div class="timeline">
                  <a href="#" class="timeline-content">
                      <h3 class="title">Web Development</h3>
                      <div class="inner-content">
                          <div class="timeline-icon">
                              <i class="fa fa-rocket"></i>
                          </div>
                          <p class="description">
                              Lorem ipsum dolor sit amet, ...
                          </p>
                      </div>
                  </a>
              </div>
              <div class="timeline">
                  <a href="#" class="timeline-content">
                      <h3 class="title">Web Designing</h3>
                      <div class="inner-content">
                          <div class="timeline-icon">
                              <i class="fa fa-globe"></i>
                          </div>
                          <p class="description">
                              Lorem ipsum dolor sit amet, ...
                          </p>
                      </div>
                  </a>
              </div>
          </div>
      </div>
    </div>
</div>
