In an HTML page, tags used are to place the content and format the pages. They always defined between (<) and (>) symbols. For example, <h1>text</h1>.

An opening tag must be preceded with a closing tag and indicated with a ‘/’ symbol.

A tag instructs the browser to format the HTML. Tags have many uses, such as changing the appearance of text, displaying a graphic, or linking another page. Coming to the other part of the question, HTML attributes are properties you can add to an HTML tag. Such attributes alter the way a tag behaves or the way it is displayed. For instance, <img> tag comes with an src attribute that you use for adding image sources. We can add attributes after the name of an HTML tag, within the brackets. Remember, we can add attributes to the opening and self-closing tag only.  No attributes are added to closing tags.
