在CSS和HTML5中替换<字体颜色：红色>文本的最佳方法是什么 </font>

Question

我有下面的文本示例，我正试图通过w3C验证器，我如何在html5和CSS中替换下面过时的<font> ?我讨厌使用<p>或<h1,2,3>，还有其他更简单的选择吗?

Tell us <font color="red"> why </font> you bought the product, and <font color="red"> when </font> you bought it.

Answer 1

使用span:

Tell us <span style="color: red;"> why </span> 
you bought the product, and <span style="color: red;"> when </span> you bought it.

Answer 2

一种方法:

<style>
    em.highlight: {
        color: red;
        font-style: normal;
    }
</style>
...
Tell us <em class="highlight"> why </em> you bought the product, and <em class="highlight"> when </em> you bought it.

我用<em>是因为你试图em强调某些词
