<span style="display:none;">search</span>
<input id="searchinput" type="text" autofocus="autofocus" placeholder="Google Search" autocomplete="off">

<!--
Insert this where you want your search bar. This is usually in a positioning div, but it's different for everyone
You might want to change:
CSS ID
placeholder (text when not clicked)
autocomplete (previous searches)
autofocus (cursor in box on load)

Note that you can also put the cursor in the text box by pressed "TAB", thanks to the JS
