📚 Formatting Guidelines
HTML Formatting Best Practices:
Indentation:
• Use 2 or 4 spaces consistently
• Indent child elements
• Align closing tags with opening tags
Attributes:
• Use double quotes for attribute values
• Lowercase attribute names
• Sort attributes alphabetically (optional)
• Wrap long attribute lists
Structure:
• One element per line for block elements
• Inline elements can be on same line
• Close all tags properly
• Use semantic HTML elements
Example:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Page Title</title>
</head>
<body>
<header>
<h1>Main Heading</h1>
</header>
<main>
<p>Content goes here.</p>
</main>
</body>
</html>
CSS Formatting Best Practices:
Selectors:
• One selector per line for multiple selectors
• Use lowercase for class and ID names
• Use hyphens for multi-word names
• Avoid overly specific selectors
Properties:
• One property per line
• Space after colon
• Semicolon after each property
• Sort properties alphabetically (optional)
Structure:
• Group related rules together
• Use comments to separate sections
• Consistent indentation
• Logical property order
Example:
.header {
background-color: #333;
color: white;
padding: 1rem;
text-align: center;
}
.nav-menu {
display: flex;
justify-content: space-between;
list-style: none;
margin: 0;
padding: 0;
}
.nav-menu li {
margin: 0 1rem;
}
JavaScript Formatting Best Practices:
Variables:
• Use camelCase for variables and functions
• Use PascalCase for constructors and classes
• Use UPPER_CASE for constants
• Declare variables at the top of scope
Functions:
• Space before opening brace
• Consistent indentation
• Clear parameter names
• Return early when possible
Structure:
• Semicolons at end of statements
• Consistent quote style (single or double)
• Proper spacing around operators
• Logical code organization
Example:
const API_URL = 'https://api.example.com';
class UserManager {
constructor(apiUrl) {
this.apiUrl = apiUrl;
this.users = [];
}
async fetchUsers() {
try {
const response = await fetch(this.apiUrl);
const data = await response.json();
this.users = data.users;
return this.users;
} catch (error) {
console.error('Error fetching users:', error);
return [];
}
}
findUserById(id) {
return this.users.find(user => user.id === id);
}
}
