Dani wants to create a web page to document her travel adventures. Which coding language should she use? HTML Java Python Text
Anna [14]

Answer:

HTML, CSS, JavaScript, python, SQL

Explanation:

To create a web page for her travel adventures Dani has to use HTML and CSS to design the page's layout. A beautiful simple design such as one which shows photos of her on her travel destinations, and a paragraph for her to write a little story on her travels would do.

Dani needs JavaScript to animate the photos she's going to post on the page. Dani also should use python to build the backend of her page so she can write codes to save and access her documented adventures from the database. She should use a database language like SQL to save all of her adventures so she can view them at a later time for the memories.
