Web Development is a career which requires various skills, but the number one rule you need to remember is to learn the basics and build on top of it. So I suggest you focus on learning the basics.
Here are the steps I'd suggest you take land a job in web development:
1.) Learn the basics XHTML / HTML5. This markup language of all web pages in websites you see everyday. My suggestion is to study the top 5 most used HTML tags and you must learn what they are used for and how do you use them.
2.) Learn the basics of CSS / CSS3 . This is a stylesheet language a CSS file will instruct the browser how we want our HTML page to appear. My suggestion here is to study just 5 topics first examples are margins, paddings, borders, display types and media queries(this is crucial since creating mobile responsive websites is a must). You must learn when to use them, how to use them and how they interact with each other.
3. Learn JavaScript this programming language will allow you to interact with every element in a webpage. I'd suggest you learn the basics of programming in general Variables, Conditional Statement, Loops, Comparison Operators, Basic Boolean Algebra after than you can study basics of JavaScript syntax, data types, operators, functions and events.
4. Learn a server-side programming language. You can choose among PHP, Python or ASP.net . Take note that It is highly recommended to focus on one language first. With this you can create programs that run on a web server to generate dynamic web pages.
5. Learn SQL and Database Management Systems. SQL is a query language you will use to interact with a database server and a database server is what hold the data used by your website running on your the web server to persistently store user information, website settings etc.,
6. Is to create a simple project Web Page(HTML) > Style & Layout(CSS) > Create a calculator(JavaScript) > Install a webserver application I suggest(XAMMP) and try to run your website on the server > Connect your website to a database MySQL will come installed with XAMPP so you can go for it. Take note that you will use PHP(server-side programming language) to create queries and interact with a database.
One thing you can do is to create a history of operations done by your calculator website.
7. Last and final step is to create your own portfolio website. Using what you've learned. Include a photo of yourself, Information about you, Sample projects(could be your personal project), Services and contact information. Also you can proudly include your portfolio website in your resume.
After this I'm confident that this will increase your chances of landing a job in Web Development.
Good Luck!
