HTML5 has grammar but mathematical logic or structural logic

  • 772

While reading this W3C document , I came across a part that made me curious:

Similarly, just as natural languages ​​have grammatical rules for how different words can be used, HTML has rules for where and how each element and attribute can be used.

Which can be translated as:

Similarly, just as natural languages ​​have grammatical rules for how different words can be used, HTML has rules for where and how each element and attribute can be used.

Logically I understand that HTML is not like languages ​​like JavaScript or Java. So my question is:

Does HTML have a mathematical logic to position the elements in a logical (mathematical) way and order so that the document makes current sense? Or is it just a hierarchical order of the DOM? (because I believe that the text refers to the logical plot that a web page has in the DOM)

Could someone expert in HTML5 explain it to me?

    In the same paragraph from which you extracted the quote you mention, it also says:

    HTML has a defined set of elements and attributes which can be used in a document, each designed for a specific purpose and with its own meaning.

    HTML you have elements for:

    • Headers
    • Paragraphs
    • Boards
    • lists
    • Links
    • etc.

    The above is the vocabulary of HTML; via tags

    In the same way, the cited document indicates that:

    HTML is a tree-like structure (which we know as the DOM) that is formed from its tags in which all the elements have a defined parent; minus the root elements

    So it is important to distinguish that HTML gives us a syntax to create a markup structure through its tags; which are interpreted by the render engine of each browser.

    It is also important to know that there are rules to know which labels may or may not contain others.
