+You can try to use this one -
+
+<div style="white-space: pre-wrap;"><code> 
+              int a = 10;
+              int b = 10;
+              int d = 10;
+</code>
+</div>
+
+And if you insist on using <pre> only and not <div> then,
+
+<pre  style="white-space: pre-wrap; word-break: keep-all;">
+<code> 
+              int a = 10;
+              int b = 10;
+              int d = 10;
+</code>
+</pre>
+
+pre { overflow: auto; }
+Using this will allow a fixed size with horizontal scrolling for long lines, which I guess is good for a blog.
+
+Just experiment with these and let me know!
