What is the difference between HTML div and span elements?

there are two tags in html , one is div and another one is span.. now I wish to know the difference between these two tags according to their functions and roles...
I tried both the tag but I didn't found any unique difference between both, so I am expecting to get the detailed answer .

Div element defines a section in a document (block-level).
Span elememt also defines a section in a document (inline).
So what's the difference between block-level and inline.
There are two types of elements in html.
Block-Level Elements.
Inline Elements.
Block-Level Element always starts on a new line and takes up the full width as possible.
Inline Elements doesn't starts on a new line and takes up as much width as necessary.
You cannot put a block-level elememt into an inline element.
Div is a block-level element and Span is an inline element.

I know that an inline box does not occupy whole width. It only takes required width. While referring a book on CSS, I learned that an Inline Box consists: Content Area (which is equal to em boxes stacked next to each other horizontally) + Leading (which itself is equal to sum of Top and Bottom leading). The height of this box is the Line height.

For Line Box, the diagram shown is this:
Line Box Diagram
My main concern here is the definition of vertical-align says that (as per MDN docs: https://developer.mozilla.org/en-US/docs/Web/CSS/vertical-align) "..vertical-align only applies to inline, inline-block and table-cell elements: you can't use it to vertically align block-level elements."
Another use case says: ".....To vertically align an inline element's box inside its containing line box."
Here the last bold term is very confusing to me. I am not able to make sense out of it and not able to visualize what these two definition says. Can any body help me with this?

Why does displaying my divs as inline cause them to overlap my h1? [duplicate]

Padding for Inline Elements
(3 answers)
Closed 2 years ago.
I'm just playing around with the border/content box CSS properties in the very early stages of learning.
Trying to make the two boxes line up next to one another- I've achieved it with using the float left and right properties.
However, when I use display inline, it causes an overlap with the above block element h1. I've displayed it as a table here, so the background colour I've set on it only spans the width of the content, but that shouldn't change the fact that it is still a block element.
More than the overlap, display: inline on the div causes the boxes to shrink in size as well.
Can anyone explain why this is happening?
Please see the code here: https://jsfiddle.net/gouvrze1/
Only block elements respect width and height rules. Inline elements just flow with their text content. The overlap is caused by the padding and the fact that the divs are further down in the DOM, so they're drawn after and on top of previous elements.
Try changing your divs to display: inline-block instead.

I know there are lots of documents on span and div but I really understood how it happens with styling part. Unless styling do we have anything change with span and div tags in HTML where the behaviour of the application changes a lot?
span element is in-line and usually used for a small chunk of HTML inside a line like inside the tag where as is used for block-line. div tag also uses line-break before and after tag.
span element is inline element it means it only takes the minimum or required space for content
see the output of span element(inline level)
while div element takes full space (100%) because it is block level element
output of div element (block level)

Why does the blue box not surround the child div-elements? [duplicate]

Why doesn't the height of a container element increase if it contains floated elements?

I published a simple example on jsbin. And I do not understand why The blue box does not surround the child elements if the childs have a float:left.
http://jsbin.com/saluxapiti/1/edit?html,css,js,output
When you set property to float.It takes your element over html surface.Looks like an air baloon.
Summarizing what this page states:
Elements after a floating element will flow around it; therefore the border of the parent class is flowing around the floated child.

This is not true as of HTML5.
What is the reason of not placing block level elements inside inline elements?
The HTML specification describes which elements may contain other elements. "Flow content" can often contain "Flow Content", or "Phrasing Content", but even this is not always the case. For example, a p element is a block level element, but it may only contain "Phrasing Content".
