I want a search bar which searches for the value and highlight that particular value in my web page. I have made a navigation bar in which there is search button with id "btn" and a text box with id "InputVal". I want that my text box value is searched and is highlighted in my webpage (paragraph).

HMS Royal Oak was one of five British Revenge-class battleships built for the Royal Navy during the First World
War. Launched on 17 November 1914, the ship first saw combat at the Battle of Jutland. On 14 October 1939, she
was torpedoed by the German submarine U-47 while anchored at Scapa Flow in Orkney, Scotland; 835 were killed
that night or died later of their wounds. The loss of the outdated ship—the first of the five Royal Navy
battleships and battlecruisers sunk in the Second World War—did little to affect the numerical superiority
enjoyed by the British navy and its allies, but the sinking had a considerable effect on wartime morale. Günther
Prien, the U-boat commander, became the first German submarine officer to be awarded the Knight's Cross of the
Iron Cross. Demonstrating that the German navy was capable of bringing the war to British home waters, the raid
resulted in rapid changes to dockland security and the construction of the Churchill Barriers around Scapa Flow.
