✅ CSS Basics You Should Know 🎨💻

CSS (Cascading Style Sheets) is used to style HTML elements — adding colors, spacing, layout, and more.

1️⃣ CSS Syntax

selector {
  property: value;
}

Example:

h1 {
  color: blue;
  font-size: 32px;
}

2️⃣ How to Add CSS
⦁ Inline:

<p style="color: red;">Hello</p>

⦁ Internal (within HTML):

<style>
  p { color: green; }
</style>

⦁ External (best practice):

<link rel="stylesheet" href="style.css">

3️⃣ Selectors
⦁ * → All elements
⦁ p → All <p> tags
⦁ .class → Elements with class
⦁ #id → Element with specific ID

#title { color: blue; }.red-text { color: red; }

4️⃣ Colors & Fonts

body {
  background-color: #f2f2f2;
  color: #333;
  font-family: Arial, sans-serif;
}

5️⃣ Box Model 
Every HTML element is a box: 
content + padding + border + margin

6️⃣ Layout with Flexbox

{
  display: flex;
  justify-content: space-between;
  align-items: center;
}

7️⃣ Responsive Design

@media (max-width: 600px) {
  body {
    font-size: 14px;
  }
}

8️⃣ Hover Effects

button:hover {
  background-color: black;
  color: white;
}

9️⃣ Common Properties
⦁ color – Text color
⦁ background-color – Background
⦁ margin & padding – Spacing
⦁ border – Border style
⦁ width / height – Size
⦁ text-align – Alignment
