✅ What are the different types of HTML5 storage?
– LocalStorage: Stores data with no expiration date.
[javascript]
localStorage.setItem(‘key’, ‘value’);
console.log(localStorage.getItem(‘key’));
[/javascript]
– SessionStorage: Stores data for one session.
[javascript]
sessionStorage.setItem(‘key’, ‘value’);
console.log(sessionStorage.getItem(‘key’));
[/javascript]

🎨 CSS Questions

✅ What is the difference between Flexbox and Grid?
– Flexbox is for one-dimensional layouts (rows or columns).

.container {
display: flex;
justify-content: space-between;
}

– Grid is for two-dimensional layouts (rows and columns).

.container {
display: grid;
grid-template-columns: repeat(3, 1fr);
}

✅ How do you create a responsive design without media queries?
Use relative units like %, em, rem, and vw/vh. For example:

.container {
width: 80%;
margin: 0 auto;
}

✅ What are pseudo-elements and pseudo-classes?

• Pseudo-classes target elements in a specific state, like `:hover` or :nth-child().

  button:hover {
  background-color: #ff6347;
  }
  

• Pseudo-elements style specific parts of an element, like `::before` or ::after.

  p::before {
  content: "→ ";
  }
  

✅ How does the z-index property work?

`z-index` controls the stacking order of elements. Higher values appear on top.

.box1 {
z-index: 1;
}
.box2 {
z-index: 2;
}
