Whether you are a beginner or an expert in Hyper Text Markup Language (HTML) it is important to follow some best practices in order to keep your HTML documents consistent and organized.
HTML5 has been around for many years now and has been stable and supported at least partially supported by most major browsers since 2014. Here I present list of best coding practices regarding HTML5 markup. Let’s get started:
-
File Structure
Be concerned to the project file structure from day one. It’s extremely important for mid to large scale application for batter maintenance.
Declare correct Doctype
If correct Doctype is not declared new HTML5-specific tags will not interpreted by the browser.
- ###Write w3c valid markup

- ###Variant class in parent element
Tried to added class in parent element if need give another style to the same block or need same block different style.

For better performance please tried to avoid unnecessary wrapping. It will create unnecessary node in your HTML tree and reduce performance too.
Bad Practice

- ###Closing tag
It is best practice to always concern with closing starting tag even if it is self-closing tag.
- ###Injecting external styleSheet
