## DOM
In this section, we will start writing the DOM tree of an HTML document or file. DOM stands for Document Object Model. The DOM is structure like a true. It starts with an _html_ root element followed by head and body. The head and the body are the immediate children of the root element, _html_.
Create folder on the desktop and give it any name and even you may call it (30DaysOfHTML), inside this folder create an index.html file. Every HTML file has to end with .html extension. And it is good to have at least on index.html file in the project and the reset of the file will have different names.

# Day 4
## Blocking and Non-blocking Elements
# Day 5
HTML elements are like a box. Some elements take the whole width of the view port while some take as much space that fit only for the content. In another way, some elements do not allow other elements to come next them both in the left and right side, however, some elements allow other elements to come next to them.
## HTML5 Semantic Elements
- Blocking elements take the whole width of the viewport.
- Non-blocking element only take a space that is enough for the content.
List of blocking elements:
```sh
<address>
<article>
<aside>
<blockquote>
<canvas>
<dd>
<div>
<dl>
<dt>
<fieldset>
<figcaption>
<figure>
<footer>
