Key Takeaways

Sometimes the data you need for a project is only available by scraping websites. Because of that it's important to be familiar with the basics of HTML and CSS and to be comfortable scraping data using a tool like Beautiful Soup. Key takeaways from this section:

• HTML is used to mark up text to provide more meaning (is this an image, an element in a list or a page title)
• Don't worry if you're unfamiliar with a given HTML tag - it's always easy to find information about it. The goal of this section was to give you a starting point - not a comprehensive understanding!
• CSS is used to style web pages
• Beautiful soup is a great package for scraping information from static websites
