Best Practices for HTML Projects

Introduction

While building websites, a lot of programmers, even experienced ones make mistakes in their code. These silly mistakes not only annoys and hurts you but also leaves you frustrated because you have a lot of errors in your project.

In this article, we are going to look at some best practices which you should follow to write a clean and clear HyperText Markup Language (HTML) code.

HTML Best Practices

In this section, we will describe some best practices to keep in mind when working on your HTML project including:

Use proper document structure with Doctype

To avoid errors or bugs, it’s a good habit to follow the proper document structure with the correct doctype. Every HTML page is made up of the <html> root element which contains the <head> and <body> elements inside it. To make web browsers understand what type of document to expect, we must also specify the DOCTYPE declaration which is <!DOCTYPE html> for HTML5. Doctype is the first thing to specify in an HTML document.

Always close tags

To avoid errors, always remember to have a closing tag to every tag you create in your code. It is also important that you don’t miss any parent or nested tags that are not closed. The exception to this rule is in the case of empty elements such as <img> and <br>.

Use lowercase markup

Your HTML markup can be written in lowercase or uppercase and the web page will be rendered correctly. However, it is best practice to keep tag names in lowercase because it is easier to read and maintain.

Use Heading elements wisely

HTML has six (6) different types of heading tags that should be used carefully. You should use these tags (<h1> to <h6>) to denote your hierarchy on a web page. It is also important that you use only one <h1> per page. Finally, heading tags play a crucial role in making your website search engine friendly.

Write a well-formatted code

Even though HTML doesn’t care about spaces, it is important to give proper space or indentation in your HTML code to make it more manageable. A cleanly written and well-formatted code shows your professionalism and increases your work’s readability. A few tips to do this include:

  • Indent nested elements
  • Strictly use double quotes, not single or completely omitted quotes
  • Use lowercase letters within element names, attributes and values

Validate your code often

While writing HTML, make a habit to validate frequently. Do not wait until the end of the project before checking for errors. This will save you from issues that are harder to pinpoint or redo once your work is completed and lengthier.

Conclusion

Maintaining practices such as using a proper HTML document structure, ensuring that all tags created in your project are properly closed, using lowercase markup, the wise use of heading elements and writing a well-formatted code helps to keep your HTML documents consistent, organized and error-free. Keep learning. Happy coding.
