• In HTML if we want to apply any styles to any elements we will use cascading style sheets.
• By using CSS we can apply styles to an element in HTML
• If some style is needed for more than one type of element then we cant make a style and name it and where ever that style is required we can place that style for that element.


• So like this it is always possible to apply multiple styles or multiple classes to HTML elements.
• We can specify more than one CSS class to an element.
• By using class attribute we can specify multiple  CSS classes to a single element and all classes must be separated by a space.
• For example if we are applying multiple classes to a div tag.
• <div class="class1 class2"></div>
• Here class is the attribute and class1 and class2 are the two different CSS classes.
• Lets take an example of one paragraph element and two css classes 
• Fist we define a <p> element with no styles.
• Second one more <p> element with one style
• Third one more <p> element with two styles.  
• HTML multiple classes
