In your html write: <link rel="stylesheet" href="style. css" /> and keep the style. css and the html file in the same folder. Just open the html file with any browser (double-click).
How do I access CSS files?
It is a clickable link, so you can also hold CTRL and click it to view the CSS file. For example, href="styles.css" if the CSS file is located in the same folder as the HTML file. Or href="folder/styles.css" if the CSS file is located on another folder.
