Question

if you do not want every diver on your web page to have the same CSS rule apply to it which selector can you use to apply a certain style to a single division

Answer 1

To apply a certain style to a single `<div>` on your web page without affecting other `<div>` elements, you can use an **ID selector** or a **class selector**.

1. **ID Selector**: This is used if you want to target one specific element. The ID should be unique within the HTML document.

Example:
```html
<div id="uniqueDivision">This is a unique division</div>
```

CSS:
```css
#uniqueDivision {
background-color: lightblue;
padding: 20px;
}
```

2. **Class Selector**: If you want to apply styles to multiple elements selectively or if you want to reuse the style for other elements, you can use a class. You can assign the class to the specific `<div>` you want to style.

Example:
```html
<div class="specialDivision">This is a special division</div>
```

CSS:
```css
.specialDivision {
background-color: lightgreen;
padding: 20px;
}
```

Using either an **ID selector** (for unique elements) or a **class selector** (for grouped styling) is an effective way to ensure that specific styles apply only to desired elements.
