To make a folder in GitHub visible in the website, there must be an index.html file inside it
Add the folders you don't want to commit via GitHub desktop to .gitignore

Mark Down and HTML
To add a line break in html, use <br>
To add a new line in markdown, use the forward slash \
To mark something as a code, incorporate it within backticks"``".

If you want to open a link in new tab - <a href="Link" target="_blank" rel="noopener noreferrer">Text</a>.
If you want to embed a file (pdf, image etc) - <div class="container"> <embed src="link"/a></div>.
If you want to change the color of a specific sentence: <span style="color:white">text_here</span>

Backlink - Issue 2
I faced an issue where nothing happened when I clicked on the back(.) link added to index files of any folder.
There are two fixes I came up for this issue.

  1. Change from <a href=".">Back<br></a> to <a href="..">Back<br></a>.
  2. Don't use back link at all or provide absolute link instead of "..".
Tip: If you want to go back two directories at once when clicking a back link, use "../..".
Add more "/.." for more directories.

    2. Inside <head>:
  2. <title>Title</title>
  3. <meta name="viewport" content="width=device-width, initial-scale=1">
