HTML is a widely used language that gives our webpage a structure. HTML stands for HYPERTEXT MARKUP LANGUAGE. HTML was created by Berners Lee in 1991.
A Physical tag has physical text which is used to tell the browser how to display the text enclosed in the physical tag.
Example for the physical tags are: <big>, <b>, <i>
Logical tags are used to tell the meaning of the enclosed text in it. The example of the logical tag is <Important>….</Important> tag. When we enclose text in Important tag then it tell the browser that enclosed text is more important than other text.
Example:
<table border cellspacing=3>
<table border cellpadding=3>
<table border cellspacing=3 cellpadding=3>
<a href="mailto:someone@example.com?Subject=Hello%20again" target="_top">Send Mail</a>

Grouping is used to group several HTML controls like input, textarea, selects as well as labels ( <label>) within a web form. In HTML <fieldset> element is used for Grouping.
The <fieldset> is a tag in HTML that is used to group related elements in a form. It draws a box around the related elements.
The difference between span and div is that a span element is in-line and usually used for a small chunk of HTML inside a line (such as inside a paragraph) whereas a div (division) element is block-line (which is basically equivalent to having a line-break before and after it) and used to group larger chunks of code.
<div id="scissors">
<p>This is <span class="paper">crazy</span></p>
</div>
