In HTML, why do we include a slash (/) in closing tags?

In HTML, the slash (/) in a tag indicates that it is the closing tag for an element. This is required because HTML uses pairs of tags to define where an element starts and ends.

For example,

This is a paragraph.

Here,

marks the start of the paragraph, and

marks the end. The content in between these tags—This is a paragraph.—is defined as a paragraph.

Without the closing

tag, HTML wouldn't know where the paragraph ends, which could cause formatting issues or incorrect rendering.

Hope this clears things up. Let me know if you have more questions.
