If you're going to use Bootstrap, use it for everything. It's much more than a layout. In this example, I used Bootstrap for layout and the responsive navbar with dropdowns across the top. In smaller devices, it collapses to a hamburger menu.

<p> Harry was the son of Ernest Binning. After his father’s death he ran the picture frame business. In this picture we see Harry in the arms of his mother Maud. Harry was born in the Holborn district in 1911 and married Betty McGrath in the same district in 1932. They had children Bryan in 1933 and Peter in 1937, both born in the Holborn district. A third child, Stephen was a "blue baby" and died shortly after birth. Harry Binning started running the business before the Second World War and continued working in the shop until his death in 1990</p>
