This lesson focused on using JavaScript to dynamically modify the style of elements on a webpage. The .style property of JavaScript provides an interface to change or add CSS styling to an element.

• The .style property lets you get or set inline styles of an element.
• It provides a way to add to or modify CSS styling of a webpage directly through JavaScript.

The general format for using .style is:

    selector.style.cssProperty = "value";

Example: To set the width of an image:

    firstImg.style.width = "400px";

• Selector: Choose the HTML element you want to style.
• .style Property: Used to access the style of the chosen element.
• CSS Property: Decide which style property you want to change.
• Value: Set the desired value for that property.

Example: To set a div's background color to purple:

div1.style.backgroundColor = "purple";

• CSS properties that have two words are written in camel case when using them in JavaScript.

• Remove any hyphens and capitalize the first letter of the second word.

  CSS	JavaScript
  background-color	backgroundColor
  font-size	fontSize

Example:

header.style.backgroundColor = "black";
header.style.color = "lightGreen";

• JavaScript provides a powerful tool in the .style property to dynamically adjust styles.
• Remember to use camel case for CSS properties that are typically hyphenated when using them in JavaScript.
