What is the main purpose of a CSS reset?

The main purpose of a CSS reset is to standardize styling across browsers. Different web browsers have their own default styles for HTML elements, which can lead to inconsistencies in how a webpage appears when viewed on different browsers. A CSS reset works by removing these default styles, creating a baseline that ensures that all elements render in a more uniform manner across different environments. This allows developers to start with a clean slate and apply their own styles without worrying about the discrepancies caused by browser-specific default settings. By using a reset, designers can achieve a more predictable and consistent presentation of web content, which is crucial for maintaining a professional and cohesive look across various platforms.
