HTML Terminology Part-1

HTML Element: as it applies to web development technology :-

An HTML element is an individual component of HTML. Elements are sometimes referred to as "HTML Tags". Elements are responsible for marking up content on web pages using tags that wrap content for specifying to the browser software how to treat the content.

HTML Tag : as it applies to web development technology :-

HTML Tag is the actual markup for an Element. Elements usually have an opening and corresponding closing tag, the tags are what makes up the element. We start a tag, place content into it, then close it making the element complete. Keep in mind that some HTML tags and elements have no closing tag and therefore cannot receive content, they(the void html elements) only receive attributes.

Block Element : as it applies to web development technology :-

An HTML block level element is one that takes up a whole display block on the page like a "div" or "paragraph" tag does. By default block level elements cannot be placed side by side horizontally on a web page.

Inline Element : as it applies to web development technology :-

Inline HTML elements do not take up a whole display block and can be laid side by side horizontally. Examples of inline elements are all of the text formatting elements and the "span" tag. The "img" tag is also an inline display element. The counterpart of an inline display element, is a block display element.

Void Element : as it applies to web development technology :-

Void elements are the HTML tags that we are not able to put content inside of, we can only give them attributes and settings. They do not have a closing tag like most other HTML elements, and they make no nest for content to be place in.

Event : as it applies to web development technology :-

In programming an "event" is a specific action or process that can occur. We listen for specific things, and then run scripted functionality in our web applications when they occur. It is known as "event handling". For example in HTML we have event handlers we can apply to our elements which are simply mechanisms that wait and listen for a specific event to happen like "onclick" of a page element.

Most programming languages also refer to events and it is a similar logic. For instance in Javascript or Actionscript we apply event listeners to our objects, and write functions in the app that stand ready to fire off if the event occurs.
