If you are editing a personal Web site, then you should already have access to the code, including the CSS selectors, through your HTML code editor. If you are editing a social media or blog site, then that Web site should provide you with an HTML editing tool, usually as part of the user interface. In most cases you will need to manually parse through the code to find the CSS selectors, but they are usually found near the beginning of the HTML code. Some of the more popular CSS selectors to look for are: H1, H2, div, body, bodycopy, header and footer.

You can also use our CSS Sucker tool to extract a list of CSS selectors used on your website. The CSS Sucker can be accessed by clicking the "Add and Edit CSS Selectors" link for your project on the Manage Web Fonts page.
