Bootstrap and html5 - section or div?

问题:

I have a question regarding using Bootstrap - I see that on default they use a lot of DIVs instead of sections etc.

I've been reading the HTML5 specification lately - when to use section and when to use div. The basic idea is that DIVs should be used only if any specific HTML5 element doesn't apply.

Now, if I want to create an HTML5 website using Bootstrap, should I change the DIVs to specific HTML elements (for example SECTION)?

回答1:

It really depends on your page's content but basically you could use HTML5 tags and apply bootstrap classes like this:

<section class="row">
    ...
</section>

<footer class="row">
    ...
</footer>

But as said it depends on your content, and even more, you're not forced to use <section> tags, they have the specific purpose to represents a generic document or application section, and they're not mandatory.

The <div> tags are generic tag usually used for styling, as in bootstrap. But if you want to keep the <section> tags, maybe you could prefer a mixed solution like this:

<section>
    <div class="row">
       ...
    </div>
    <div class="row">
      ...
    </div>
</section>

With this solution the <section> tag is used for grouping contents, as it should be, and the <div> tags for styling it.

Section is not for design purpose, it has specific meaning. It indicates separate sections/parts of a web page. On the other hand, div has no specific meaning. You can use divs anonymously for managing your front-end styles.

As far as I've read using section is correct semantics and helps with SEO.

Section tags are used to segment your web pages and makes it SEO optimized while divs are used for styling your contents.
