As an SEO expert, you don't need to be a programming whiz. But having a basic understanding of HTML, CSS, PHP, and JavaScript can make you a billion times better at your job. CSS is an incredibly useful tool for web design, and it can also help you improve your ranking on the search engine results page. Using external CSS files to design your website will result in cleaner HTML code and better search engine rankings.
You can also use CSS to tell search engines how important your content is by displaying it above the navigation bar in your website's code. If you want to become an SEO, learning and understanding HTML and CSS is an integral part of that process. If you already have a website and want to improve search results, convert your table-based programming to CSS. Once you've learned how to use CSS to improve SEO, it's important to pay attention to your actual content.
You don't need to be an expert in HTML and CSS programming with a complex knowledge of all the HTML parameters. However, there is a basic HTML & CSS code that you can find, and knowing some basic knowledge about the HTML and CSS programming languages can help you do SEO more effectively. If you read SEO tutorials from more than 3 years ago, you might even find steps to block Google in your CSS or JavaScript.
