 <p>
         This latter form is somewhat more natural in that it corresponds with the
         usual definition of a continued fraction, but note that the first <span class="emphasis"><em>a</em></span>
         = 1.618033989...</a> can be computed from the simplest continued fraction
         of all:
       </p>
-<p>
-        <span class="inlinemediaobject"><img src="../../../equations/fraction3.svg"></span>

+          <span class="inlinemediaobject"><img src="../../../equations/fraction3.svg"></span>
+
+        </p></blockquote></div>
 <p>
         We begin by defining a generator function:
       </p>
         and the <span class="emphasis"><em>b</em></span>'s when evaluating special functions by continued
         fractions, for example the tan function is defined by:
       </p>
-<p>
-        <span class="inlinemediaobject"><img src="../../../equations/fraction4.svg"></span>
-      </p>
+<div class="blockquote"><blockquote class="blockquote"><p>
+          <span class="inlinemediaobject"><img src="../../../equations/fraction4.svg"></span>
+
+        </p></blockquote></div>
 <p>
         So its generator object would look like:
       </p>
         Now we'll look at a couple of complex number examples, starting with the
         exponential integral which can be calculated via:
       </p>
-<p>
-        <span class="inlinemediaobject"><img src="../../../equations/expint_n_3.svg"></span>
-      </p>
+<div class="blockquote"><blockquote class="blockquote"><p>
+          <span class="inlinemediaobject"><img src="../../../equations/expint_n_3.svg"></span>
+
+        </p></blockquote></div>
 <p>
         So our functor looks like this:
       </p>
         there is only one special function in our code which uses that variant, and
         it's the upper incomplete gamma function (Q), which can be calculated via:
       </p>
-<p>
-        <span class="inlinemediaobject"><img src="../../../equations/igamma9.svg"></span>
-      </p>
+<div class="blockquote"><blockquote class="blockquote"><p>
+          <span class="inlinemediaobject"><img src="../../../equations/igamma9.svg"></span>
+
+        </p></blockquote></div>
 <p>
         In this case the first couple of terms are different from the rest, so our
         fraction will start with the first "regular" a term:
