- All websites are written in HTML

- HTML is a descriptive markup language. In our case it describes the content part of a website.Like words, images, videos etc...
- The parts that describe this content are called elements or tags.
- Elements can be inside other elements just like a content can wrap other content.
- In this case the element inside/nested element is called/reffered as the child of its encasing/outer element. Also the encasing/outer element is called parent element.
index.htmlfile is the default file loaded if no other file is specified.
- HTML syntax is used to write the HTML files using lots differernt elements which come together to form a web page.
- All HTML Elements follow the same format.
- Write the name of the element inside angular brackets and then you can write the content after. Then we close the element by writing the same element again, inside angular brackets, but this time put a forward slash "/" after the first angular bracket.

- First thing need is a doctype declaration to the program this is a HTML documnent and specifically we'll be using HTML5.
<!doctype html>
- Everything inside a HTML file is written inside a
htmlelement. - It is always a good practice to close the element at same time to you open the element.
- Specify language used in HTML file with the
langattribtue<html lang="en">
- Inside the
htmlelement there are two important child elements we need.headandbodyelements.- Everything the browser shows the user is written inside the
bodyelement. All of the content. - Most of the work is done inside the
bodyelement.
- Everything the browser shows the user is written inside the
- The
headelement gives more information about the documnet itself. - Most of this information is not shown to the user.
