📘 DAY 12: HTML CSS 


1️⃣ What is CSS?

CSS stands for Cascading Style Sheets.

CSS is used to:

  • Style HTML elements

  • Control layout and design

  • Improve user experience

👉 HTML = structure
👉 CSS = design

2️⃣ Why Do We Need CSS?

Without CSS:

  • Pages look plain

  • No colors or layout

  • Poor readability

With CSS:
✔ Attractive design
✔ Consistent styling
✔ Easy maintenance

3️⃣ Ways to Apply CSS in HTML

There are three ways to apply CSS:

  1. Inline CSS

  2. Internal CSS

  3. External CSS

4️⃣ Inline CSS

Inline CSS is written inside the HTML element using the style attribute.

Syntax:

<tag style="property:value;">

Example:

<p style="color:red; font-size:18px;">
  Inline CSS Example
</p>

✔ Advantages

  • Quick styling

  • Easy for beginners

❌ Disadvantages

  • Not reusable

  • Messy code

  • Not recommended for large pages

5️⃣ Internal CSS

Internal CSS is written inside the <style> tag in the <head> section.

Syntax:

<head>
  <style>
    p {
      color: blue;
      font-size: 18px;
    }
  </style>
</head>

Example:

<!DOCTYPE html>
<html>
<head>
  <style>
    h1 {
      color: green;
      text-align: center;
    }
    p {
      color: blue;
    }
  </style>
</head>
<body>

<h1>Internal CSS</h1>
<p>This is styled using internal CSS.</p>

</body>
</html>

✔ Advantages

  • Better than inline

  • Styles multiple elements

❌ Disadvantages

  • Not reusable across pages

6️⃣ External CSS

External CSS is written in a separate .css file and linked to HTML.

Step 1: Create CSS file (style.css)

h1 {
  color: purple;
  text-align: center;
}

p {
  font-size: 18px;
  color: gray;
}

Step 2: Link CSS file in HTML

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

✔ Advantages

✔ Reusable
✔ Clean HTML
✔ Best practice
✔ Used in real projects

❌ Disadvantages

  • Slightly complex for beginners

7️⃣ CSS Selectors (Basic)

Selectors choose which HTML elements to style.

Element Selector

p {
  color: blue;
}

Class Selector

.text {
  color: red;
}

HTML:

<p class="text">Hello</p>

ID Selector

#main {
  font-size: 24px;
}

HTML:

<h1 id="main">Title</h1>

8️⃣ Priority Order of CSS (Very Important)

2️⃣ Internal CSS
3️⃣ External CSS (Lowest priority)
