The importance of assigning unique identifiers to HTML <section> elements

I recently acquired an HTML template with various sections, but I am unsure about some of the details.

One section in the file appears like this:

<section id="section-name" class="row"> 

</section>

Although I have seen simple <section> </section> tags before, I am confused by a few things. Specifically, what is the purpose of the section ids? Do they correspond to CSS styles or can they exist independently from CSS? Upon reviewing my CSS file, I could not find any references to the section names used, leading me to believe that the ids are simply named for organizational purposes.

Is it accurate to assume that section ids are not tied to CSS? Or could they potentially be linked to CSS properties while still functioning without direct CSS connections?

Answer №1

The purpose of the id attribute within a section is identical to its function in any other HTML element.

  • You are able to hyperlink to it using a fragment identifier at the end of a URL
  • You can style it with CSS
  • You can manipulate it with a programming language (e.g. client-side JavaScript).

Sections do not have any special treatment when it comes to handling the id attribute.

Answer №2

Think of it like a special identifier for the tag. While not necessary in CSS, you have the option to utilize it.

Answer №3

To add style to sections in css, you can use the following methods: css:

section
{
color:red;
}

or

section#section-name
{
color:red;
}

or

section.row
{
color:red;
}

or

section#section-name.row
{
color:red;
}
