CSS (Cascading Style Sheets) is a stylesheet language used to describe the look and formatting of a document written in HTML (Hypertext Markup Language). CSS selectors are used to select elements in an HTML document and apply styles to them. In web scraping, CSS selectors can be particularly useful for selecting specific elements on a webpage when the HTML structure is complex or does not have convenient class or ID attributes.
Some CSS selectors that can be particularly useful for web scraping include the
:first-child selector, which selects the first child element of a parent element,
:nth-of-type selector, which selects elements based on their position among siblings of the same element type,
~ (sibling) selector, which selects elements that are siblings of a specified element.
