To change the padding on the right side of an element, we use the padding-right property.

<html>
<head>
<style>
.leftWing {
padding-right: 200px;
background-color: lightBlue;
}

.rightWing {
padding-left: 200px;
background-color: crimson;
}
</style>
</head>
<body>

<p>The terms "left-wing" and "right-wing" were coined during the French Revolution of 1789. When drafting a new constitution:</p>
  <p class="leftWing">People who were more conservative assembled on the right side of the assembly hall, leading to the term "right-wing".</p>
  <p class="rightWing">People who were more liberal assembled on the left side of the assembly hall, leading to the term "left-wing".</p>
</body>

Make sure to type padding-right.
