I am told these warnings impact SEO. True? How does that happen?

<div class="content wysiwyg-content">
I need to find and fix the following CSS errors on my site...<br />
<br />
<a href="https://validator.w3.org/nu/?doc=http%3A%2F%2Fwww.fortressharvard.com%2F" rel="ugc nofollow">https://validator.w3.org/nu/?doc=http%3A%2F%2Fwww.fortressharvard.com%2F</a><br />
<br />
but am not sure where to begin.<br />
<br />
I do have an Admin log-in and am curious how and where to make these fixes. I will do a push to BitBucket before I do any experimentation...<br />
<br />
I was told it would take 6-8 hours to complete, and suspect that removing things flagged as unnecessary may not be as simple as it sounds.

WordPress, CSS and SEO

Web development includes all aspects of presenting content on intranets and the Internet, including delivery development, protocols, languages and standards, server software, browser clients, databases and multimedia generation.

Web Development

Search Engine Optimization (SEO) is the process of improving the visibility of web content in search engines using an understanding of search engines' processes and algorithms. Also known as "natural" or "organic" search, it is distinct from paid web advertising. Performance is typically measured by testing the appearance of a website for targeted search terms, and more specifically, ranked positions in search for important keywords. Techniques focus on content optimization, technical optimization and link building.

Search Engine Optimization (SEO)

Cascading Style Sheets (CSS) is a language used for describing the look and formatting of a document written in a markup language. Usually used to change web pages and user interfaces written in HTML, it can also be applied to any kind of XML document. CSS is designed primarily to distinguish the content of a document from its presentation.

Web development can range from developing the simplest static single page of plain text to the most complex web-based internet applications, electronic businesses, and social network services using a wide variety of languages and standards, including the familiar HTML, JavaScript and jQuery, ASP and ASP.NET, PHP, ColdFusion, CSS, PHP, Flex and Flash, but also the implementation of a broad list of standards including XML, WSDL, SSDL, VoiceXML and many more.

Web Languages and Standards

WordPress is a free and open-source content management system (CMS) based on PHP and MySQL for creating websites and blogs. Features include a plugin architecture, a template system and strong management, customization and search systems; through its dynamic presentation of content, webmasters have the flexibility to create websites easily.
