HTML (or Hyper Text Markup Language) is the standard markup language for building websites and webpages. Using what is known simply as “markup,” HTML describes the structure of webpages.
A significant portion of HTML is made of tags. If you are unfamiliar with tags, don’t be alarmed. “Tag” is simply a jargon term that denotes the individual elements that make up the HTML document.
For example, the tags of an HTML document would be the information that gives the page its structure, form, and information, such as “body,” “header,” etc. These tags allow the webpage to read the data and display accordingly.
HTML is not case sensitive, though the information inside of it is. This means that one should be careful when inputting data into an HTML document and carefully check whether or not the program is reading and displaying inputted data correctly. Clarity is important when inputting any written data into an HTML file.
Furthermore, HTML files are browser specific. This is an important piece of information that anyone just getting into HTML coding must know. What this means, in simple terms, is that you cannot use HTML coding universally for all browsers.
Though all browsers support HTML in some form or fashion (again, they MUST, as webpages are built off HTML), not all browsers read all elements of HTML. This means that you should work with your HTML coding so that you have a page that looks great on ALL browsers, not just one.
For example, you should not design a page using just Google Chrome, as there is no guarantee that the layout and format of your site will look the same when visited on Mozilla Firefox. You must remember that HTML is a widely-used and varied language, and you should accommodate accordingly when using the code for your webpages.
That being said, the basic elements of HTML are not too difficult, and they are some of the first to be taught in any computing or networking course. Having an understanding of HTML is essential for any type of advancement in web design fields.
Because of this, it can be said that HTML coding is one of the most important—and one of the most influential—types of coding around, so it is important to take it seriously and master it before moving onto more complicated material. Doing so will ensure that you have the necessary foundation to succeed in the computing market.
