Differentiate between the use of ID selector and class selector.

ID selectors and class selectors are two types of CSS selectors that are used to apply styles to elements in a webpage. The main difference between the two is how they are used to select elements:

ID Selectors

ID selectors are used to identifying a single, unique element on a webpage. They are denoted by a "#" symbol followed by the ID of the element. For example, #my-element would select the element with the ID "my-element". ID selectors are typically used to apply styles to elements that are not repeated on the page, such as a header or footer.

<div id="id_selector"></div>

#id_selector{
  <!-- Select with # -->
}

Class Selector

Class selectors are used to identifying a group of elements on a webpage that share the same class name. They are denoted by a "." symbol followed by the class name. For example, .my-class would select all elements with the class "my-class". Class selectors are typically used to apply styles to elements that are repeated on the page, such as links or buttons.

<div class="class_selector"></div>

.class_selector{
  <!-- Select with (.) -->
}

Another difference between ID selectors and class selectors is the specificity of the styles they apply. Styles applied with an ID selector have a higher specificity than those applied with a class selector, meaning that they will override any conflicting styles applied with a class selector. This is important to consider when designing a webpage, as you may need to use more specific selectors to ensure that your styles are applied correctly.
