An HTML Element is an individual component of an HTML document or web page. HTML is composed of a tree of HTML elements and other nodes, such as text nodes. Each element can have HTML attributes specified. Elements can also have content, including other elements and text. Many HTML elements represent semantics, or meaning. Wikipedia.org.
Example: The paragraph element <p></p> is made up of the opening <p> and the closing </p> tags.
About HTML Elements
HTML is a markup language which means that it is written with codes that can be read by a person, without needing to be compiled.
An HTML element is the opening tag that kicks off and tells the browser that everything between that and the closing tag in an HTML document.

About The Word
A trackback is one of four types of linkback methods for website authors to request notification when somebody links to one of their documents. Wikipedia.
Example: If I’m writing about a subject, and I find an article that I think makes a bunch of good points about the issue, I can link to their page as usual. But if both my site and the owner of the linked site are trackback-enabled, then my link automatically creates a notification that will inform the linked site of the new connection. This notification also provides links back and forth between the two pages, allowing readers to easily follow related streams of information
About The Word
Trackbacks have been in use since 2002, and there are currently efforts to make it’s usage an internet standard through the IETF. Though trackbacks can be very helpful, many bloggers have stopped using them. This is mostly due to some companies who have abused the feature, linking to spam sites. Though spam filters exist, the headache of having to sift through spam has led to a decline of trackback usage. On WordPress, trackbacks must be created manually, this process is explained by the first “More Information” link below.
A query is a request of information from a database. Webopedia.com.
Example: The database query retrieved the records of all employees who work more than 40 hours per week.
About The Word “Query”
Queries are most often used in SQL (structured query language), developed by IBM in 1974. This language allows a user controlled set of data to be returned from a very large collection of information.
An example SQL query
WordPress also utilizes SQL in its own unique way, with a class called wpdb, which contains its own function to relate WordPress to a database. Using the object $wpdb, a sample query for use in WordPress would look like this:
Of or relating to the part of a software system or online service that the user does not interact with and that is usually accessible only to programmers or administrators: back-end software. The Free Dictionary.
Example 1: The IT administrator logged in to the back-end of the program to change user permissions for the manager.
Example 2: Our company is seeking a Junior Full Stack Developer, who will work with back-end code, as well as front-end user interface design.
With business software, the term back-end can refer to anything customers and most employees never see, such as database queries and code. With websites, the back-end is virtually anything not seen on the front-end by normal visitors to the site.
With WordPress however, the term back-end refers to something specific:
The back end is the area that authorized users can sign into to add, remove and modify content on the website. This may also be referred to as “WordPress”, “admin” or “the administration area”. WordPress Codex Glossary.
The back-end of WordPress is primarily the administrator panel, but also includes anywhere you can post or modify content or settings. When used as a verb rather than a noun, adding content is a back-end action which requires login and privileges on that blog. On the other hand, commenting, liking, and sharing are front-end actions available to site visitors.
The Other Back-End
WordPress technically has more than one back-end. Users of WordPress.org open source software can modify settings in code to change the appearance and behavior if their installation of the software.
Example : A WordPress freelance developer modifies code on the back-end of the software to change the appearance of administrator panel for their client. The client has no access to the code, and modifies content by logging into their back-end: the administrator area.
Additionally, the developers of WordPress software itself modify code within the software when they release new versions. For WordPress software developers, the front-end of their product is the administrator panel interface, since their primary audience is blog owners, while the blog owners primary audience is their blog visitors.
Example : WordPress.org hires back end developers to work on the code of their software. They release new versions, which website developers download and set up for their clients.
In the above example, each of these three persons have their own understanding of back-end access. One client’s back-end is another developer’s front-end.
WordCamp: WordCamps are informal, community-organized events that are put together by WordPress users like you. Everyone from casual users to core developers participate, share ideas, and get to know each other. WordCamp Central
WordPress Plugin: A WordPress Plugin is a program, or a set of one or more functions, written in the PHP scripting language, that adds a specific set of features or services to the WordPress weblog, which can be seamlessly integrated with the weblog using access points and methods provided by the WordPress Plugin Application Program Interface (API). Writing a WordPress Plugin – WordPress Codex
WordPress Plugins are a set of files that have to be installed and activated in order to work. Don’t confuse WordPress Plugins with plug-ins for light bulbs or electronic devices. WordPress Plugins extend the functionality of WordPress, allowing it do do more. Continue reading WordPress Words: Plugins→
The term HTML stands for Hypertext Markup Language. This is the language that the browser understands in order to bring you the contents of you web page. According to the article “HTML- HyperText Markup Language” on Webopedia, “HTML defines the structure and layout of a Web document by using a variety of tags and attributes.”
HTML consists of tags that hold the design and structural elements of a web page such as the header, headings, lists, images, and content in general. CSS (Cascading Style Sheets) hold the instructions to design the HTML architecture of a site, influencing colors, positioning, size, and design elements.
HTML in WordPress
HTML is the underlying architecture of a web page. In WordPress, HTML is found in WordPress Themes, holding the PHP and WordPress code to generate and display the web page.
HTML is generated when creating a post or Page in WordPress. The user has two choices when creating content in WordPress, using the Visual Editor that hides the HTML tags, or using the Text Editor that displays the HTML tags.
In the post or Page Edit Screen, there are two tabs above the content and toolbar area to the right labeled Visual and Text. The Visual Editor is where you can type in what it is you would like to say, and then WordPress does all the code for you automatically. The Text tab is the “behind the scenes” of what you’ve written in the visual editor. This will show you where all the tags that are surrounding your tags and giving them certain attributes.
Adding Some Style
HTML allows you to build a base structure of how you want your page to look. You can think of HTML as the bones of your website. However, without Cascading Style Sheets (CSS) you’re websites appeal may fall flat. Alexandrea Chaudoinwrote an article for ClarkWP about what CSS is, and what it can do to give your site the extra push it deserves.
