Questions on Div and Nav tags

Question

I am working in Dreamweaver cc on a Mac.

I'm trying to learn Bootstrap.

When it comes to a class and an id in a div is this how correct?

A div's class is an identifier name within a div for the css to find in order to give the div css style attributes, such as color, padding, ect....

What is a <nav> tag? It looks like it does the same thing as a <div>

Nancy OShea · Accepted Answer

<nav> is the semantic HTML5 tag for navigation. Semantic tags give meaning and purpose to the div. And semantic tags can be re-used on a page if needed.

the questions that you ask are above Bootstrap... they are on the basis of learning what is HTML...classes are a way to give an access to elements (as group) by the CSS and/or the Javascript.... you also have an other type of attribute , id, that also allow to do that, but that time not as a group of elements, but by a unique element...class - HTML | MDN id - HTML | MDN now to understand the difference in between

and

... you have to understand that both are block element, so in appearance they can seams to act the same... and anyway they act the same... but that is in a pure structural way...now in a semantic way they are completly different, because

is a block element that group all the nested childs that it contains as a , and

group all the childs that it contains as elements refereing to a

: The Content Division element - HTML | MDN

: The Navigation Section element - HTML | MDN HTML is a pure structural meta language, so it divide content in elements. Those element by nature can be of two ways... blocks, or inline...i.e a

paragraph is a block in within an

article, which is an other block in the page .... block are independent and can be move to be displayed...inline are solidary from their container... i.e a element in a phrase is inline with this phrase, as will be a link or a
back return...now all those element block and inline must have a signification for the reader (browser, third part application, screen reader... and so on)... so we need to place a meaning to those elements in a more semantic way... and that is where the meaning of all tags reside...read this fabulous article from John Allsopp... https://alistapart.com/article/semanticsinhtml5 Can this help you? does it answer to your question ? or was it beside it ?
