Styling the Application with CSS; After building the core functionality, I created the CSS stylesheet to improve the user experience and visual appearance of the application. The stylesheet is responsible for the overall layout, typography, spacing, colors, and responsiveness of the Markdown Previewer. I used CSS to create a clean split-screen interface between the editor and preview pane, making it easy for users to write and view Markdown simultaneously. Additional styling was added for buttons, code blocks, blockquotes, lists, and other rendered Markdown elements to ensure the preview closely resembles how Markdown is typically displayed on modern platforms. The stylesheet also helps maintain consistency throughout the application while keeping the interface simple, readable, and user-friendly. Once the functionality was working, I focused on styling the application to make it more visually appealing and easier to use. Using CSS, I designed the layout, styled the editor and preview sections, and improved the appearance of rendered Markdown elements such as headings, lists, code blocks, and blockquotes. This step helped transform the project from a functional prototype into a more polished application that provides a better user experience.
