Introduction to HTML5 and CSS3

HTML5 Essentials

  This week we learned about the basics of Web Development, which is HTML5 and CSS. HTML5 is used for structuring the web page, whiles CSS provides the formatting and look for the web page. In order to work as a web developer or an app developer, you must be able to know and master HTML5 and CSS efficiently. HTML5 is a hypertext markup language version 5 and CSS means cascading style sheet. When HTML and CSS are used together with JavaScript, they create web pages that easily adapt to smart phones, tablets, gaming devices, smart TVs, as well as traditional computers. The process of a web page or an app being able to adapt to any type of device is known as responsive design. HTML, CSS, and JavaScript as a group are known as the Web Development Trifecta.

    We also covered W3C and what it does. The meaning of W3C is World Wide Web Consortium. The W3C regulates the development of HTML and CSS standards.
We also discussed about the HTML5 structure elements. The HTML5 structure elements define a document structures. When these elements are used, they make coding a web page much easier. Some of these elements are < header>, <main>, <nav>, <section>, <article>, <aside>, and <footer>.
<header>: what the top of the page would look like.
<main>: tells what the main content would be.
<nav>: provides links to other pages relating to the content.
<article>: the main content
<aside>: advertisements, feeds etc.
<footer>: gives information about the site's copyrights, owner contacts etc.
When using these elements, you must use them in tags. You Must always have an open tag and especially a closing tag, if not the command giving will keep repeating.
Last but not the least, we learned about validation. Validation is the process of checking your code to verify that it complies with the syntax rules. After you are done correcting errors, a validator will confirm that your coding is validated and ready to be published. One thing that everybody must know is that validating is always not perfect. Sometimes it does not understand codings that are not in the standard rules, but it is always good to validate a coding just to make sure that everything is what you want it to be. I hope you learned something from my blog.
