Used some basic styling and flex properties to achieve the given task.

Nice work @Vaibhav-Kumar-K-R, here are a few things to review

• All content should be wrapped within landmarks. Wrap a main tag around the .container.
• To improve the semantic meaning of these social media links, you should use the a (anchor) tag instead of the button tag. The a tag is used for navigation to other pages, while the button tag is designed for interactive actions like submitting forms or for events like toggling content. Also, using an unordered list ul to group the social media links is a better approach for both semantics and accessibility.
• It's best practice linking Google fonts directly in the HTML head section rather than directly in your CSS file as it enables asynchronous downloading, improving page load times.
• Font-size should be written in rem not px. This article explains it better Why font-size must NEVER be in pixels.
• Consider using a modern CSS reset at the start of the styles in every project. Like this one Modern CSS Reset. This will help reset a list of default browser styles.
