HTML 和用于突发新闻自动收报机的 CSS

Question

我正在努力让"Breaking"这个词在它所在的盒子中居中。我也在努力使滚动连续，现在延迟太多了。我还希望"突破"和"测试"标题脱颖而出，并且更加大胆。现在编码已经完成，并且可以工作。只是一些小的调整。还有没有可能使我在"中断"和测试中键入的任何内容也成为链接？

Answer 1

我正在努力让"打破"这个词在它所在的框中居中

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

删除→左填充：0px;

我还希望"打破"和"测试"标题站得住脚 出来，更大胆。

只需添加字体粗细：粗体;

也可以使我输入的任何内容进入"打破"并测试" 也是链接吗？谢谢！

是的，将您的 span 替换为<a>标签，并且您的"TEST"已经<a>标签

顺便说一下，根据 caniuse.com <marquee>标签已被弃用，所以你不应该使用它

但这是我所做的

使用此 CSS3 动画而不是选框
