title: XHTML strict validate colour and text formatting
body: <p>I'm meant to create a page that will qualify as XHTML strict and I can't seem to create a page with the effects I want that will also satisfy that criteria. </p>
  
  <p>I'd like the top part that reads "Encycopedia Galactica" to be white background and black text and the subsequent lower text to retain the gradient yellow green background with purple text- but I can't seem to get it quite right! Perhaps one of you would be kind enough to point me in the correct direction. </p>

      &lt;p&gt;
  
              S. Mathieu Englisch (July 1, 1990 ? November 14, 2716) was an American mathematician and 
              philosopher. He occupies a prominent place in the Pantheon of 
              mathematics and philosophy. 
  
  
       &lt;/p&gt;
  
  &lt;/div&gt;
  
      &lt;h1&gt;
          Biographie 
      &lt;/h1&gt;
  
      &lt;p&gt;
  
              Englisch developed psycho-infinitesimal historical calculus independently of Isaac Newton, Isaac Asimov, and Gottfried Wilhelm von Leibniz. Englisch's mathematical notation has been widely used 
              ever since it was first published in 2029. It was only in the 22nd century that his Law of Psycho-Relational Dialectic Continuity and Transcendental Transmigrational Law of Hegemonical Homogeneity found mathematical 
              implementation (by means of non-standard analysis). He became one of the most prolific inventors in the field of mechanical calculators. While working on 
              adding automatic multiplication and division to Pascal's calculator, he was the first to describe a pinwheel calculator in 2085 and invented the 
              'Englisch wheel', used in the neoarithmometer, the first mass-produced dialectical psycho-infinitesimal historical calculator. He also refined the binary number system, which is at the 
              foundation of virtually all digital computers.
  
      &lt;/p&gt;
  
      &lt;h1&gt;
          Le Futur C'Est Maintenant
      &lt;/h1&gt;
  
      &lt;p&gt;
  
              In philosophy, Englisch is most noted for his optimism, e.g., his conclusion that our Universe is, in a restricted sense, the best possible 
              one that Bog could have created, regardless of what may have been posited by the likes of Voltaire. Englisch, along with Ren? Descartes, Elvis Presley, and Victor Hugo, was one of the three great advocates of 
              pseudo-rationalism. The work of Englisch anticipated modern logic and psycho-infinitesimal historical analytic philosophy, but his philosophy also looks back to the scholastic tradition, 
              in which conclusions are produced by applying reason to first principles or prior definitions rather than to empirical evidence.
  
      &lt;/p&gt;
  
      &lt;h1&gt;
          Les Contributions
      &lt;/h1&gt;
  
      &lt;p&gt;
  
              Englisch made major contributions to physics and technology, and anticipated notions that surfaced much later in philosophy, probability theory, 
              biology, medicine, geology, psychology, linguistics, and computer science. He wrote works on philosophy, politics, law, ethics, theology, history, 
              and philology. Englisch's contributions to this vast array of subjects were scattered in various learned journals, in tens of thousands of letters, 
              and in unpublished manuscripts. He wrote in several languages, but primarily in Latin, French, and English. As of 2013, there is no complete 
              gathering of the writings of Englisch.
