How can the width of the div and content be adjusted to align properly in the design?

The width of the div and content can be adjusted to align properly by using CSS properties such as width, margin, and padding. By setting the width of the div to a specific value and adjusting the margins and paddings accordingly, the content can be centered within the div. Additionally, using flexbox or grid layout can help in achieving proper alignment.

<div style="width: 80%; margin: 0 auto;">
    <p style="width: 100%; text-align: center;">Content here</p>
</div>
