Folder structure:

• components: reusable components. For example: c-pager
• layout: layout styles, like header, footer, sidebar
• pages: context specific styles. For example: contact-us
• utilities: utility helper classes with single function. Often using !important to boost their specificity. For example: u-text-center

Real Programmers don’t comment their code. If it was hard to write, it should be hard to understand.

Six Stages of Debugging

1. That can’t happen.
2. That doesn’t happen on my machine.
3. That shouldn’t happen.
4. Why does that happen?
5. Oh, I see.
6. How did that ever work?

https://jsfiddle.net/07x1tek8/1/

Insert javascript file into document dynamically via javascript:

(function () {
	var script = document.createElement('script');
	script.type = 'text/javascript';
    script.src = 'https://code.jquery.com/jquery-3.3.1.min.js';
    document.head.appendChild(script);
	// document.body.appendChild(script);
	
	setTimeout(function(){
		$('div').slideUp(5000);
	}, 5000);
}());

Insert CSS file into document dynamically via javascript:

(function () {
	var styles = document.createElement('link');
	styles.rel = 'stylesheet';
	styles.type = 'text/css';
	styles.href = 'https://cdnjs.cloudflare.com/ajax/libs/animate.css/3.5.2/animate.min.css';
	document.head.appendChild(styles);
	document.body.classList.add('animated', 'infinite', 'shake');
}());

Try to isolate the issue. Copy the code that you have issues with and paste it into the clean page template.

Can you still reproduce the issue? If no – than you are missing some code from the main template. If you still can reproduce the issue than continue reading.

Now you need to start removing parts that you think are irrelevant. You should remove parts one by one with fairly small pieces of code. Refresh the page after each code remove and check if you still can reproduce the issue.

Can you still reproduce the issue? If yes – try to remove the next piece of code. If no – bring the last removed piece of code (with Ctrl+Z or what ever hot key is in your laptop). Now you found the piece of code where the issue might be. This should give you a clue to locate the issue and ways to fix it.

Changelog

Guiding Principles:

• Changelogs are for humans, not machines.
• There should be an entry for every single version.
• The same types of changes should be grouped.
• Versions and sections should be linkable.
• The latest version comes first.
• The release date of each version is displayed.
• Mention whether you follow Semantic Versioning.

Types of changes:

• [Added] for new features.
• [Changed] for changes in existing functionality.
• [Deprecated] for soon-to-be removed features.
• [Removed] for now removed features.
• [Fixed] for any bug fixes.
• [Security] in case of vulnerabilities.
