Tags which are not commonly known by begginers such as "spane", I myself don't know what is the purpose of "spane" tag. So lets explain these tags.

Hello everyone, I want you to explain some tags such as <span> I don't know this likewise there are so many tags that are rather new and difficult to get the hang of. So please explain some tags here from your side too. Thanks, Rizwan

And what is "mapping"?

[Ingolme]

Span is a generic inline element. Its purpose is to apply CSS styles to a portion of text.

<p>This text has a <span class="special">special</span> word.</p>

In the CSS stylesheet:

.special {  font-size: 1.2em;  font-style: italic;  font-variant: small-caps;}

I can't tell you what "mapping" is unless you show me the context in which the word is used.

I assume you mean <map> ? I could attempt to explain, however I think w3schools has already done a better job than I would: "The <map> tag is used to define a client-side image-map. An image-map is an image with clickable areas.The name attribute of the <map> element is required and it is associated with the <img>'s usemap attribute and creates a relationship between the image and the map.The <map> element contains a number of <area> elements, that defines the clickable areas in the image map."
