html - HTML和CSS，用于重大新闻报道

我正在努力使“ Breaking”一词在其所位于的Box中居中。我也正在努力使滚动保持连续，现在有太多延迟。我也想让“突破”和“测试”标题脱颖而出，并变得更大胆。现在，编码已完成，并且可以正常工作。只是一些小的调整。是否也可以使我输入的所有“ breaking”和“ test”链接也一样？

最佳答案

我正在努力让“突破”这个词在盒子里居中

.breaking-news-title {
    text-align: center;
    font-weight: bold;
    padding-top: 7px;
    height: 30px;
}

删除→左填充：0px;


  我也希望“突破”和“测试”标题能站得住脚
  出去，并变得更大胆。


只需添加font-weight：粗体；


  也有可能使我输入的任何内容都“破坏”并进行测试”
  也是一个链接？谢谢！


是的，将您的跨度替换为<a>标签，并且您的“ TEST”已经是<a>标签

并根据caniuse.com的方式<marquee>标签已被弃用，因此您不应使用它

http://caniuse.com/#search=marquee

但是这是我所做的编辑

使用此CSS3动画代替字幕

EDIT对您的代码进行了类似的设计
