         <p>Control structured are ways to control the direction of a program based of a given condition. A  useful  analogy to keep in mind is the way that conditions may make you choose one route over another when driving, be it the amount of traffic or the overall distance of the path. Now there is significantly less variability in the nature of the conditions used in programming, however we can highlight a few of the condition types:</p>
         <ul>
             <p><strong>Conditional:</strong> This includes if and switch statements, this primarily checks if a described condition has been met and executes a block of code based of that.</p>

         <h3>If statements</h3>
         <p><strong> What is an if statement?</strong><br> An if statement is a conditional structure that checks <strong>if</strong> a given condition is true and executes the applicable block of code if true.</p>

         <p> It follows the general syntax:</p>
         <pre><code>
-            if  *condition*:
-                *block of code*
+            if  <i>condition</i>:

         </code></pre>
         <p>Here indentation is important to denote that the block of code is in the scope of the if statement.
