I'm using the placeholder attribute on input fields like they do in my Bootstrap examples, but it doesn't show up in my of my elements. Am I missing something? Is there some doctype that I'm missing? I'm using it like in the examples on Boostrap, seemingly a simple attribute, but nothing shows up.
<!doctype html> <!--[if lt IE 7]> <html class="no-js lt-ie9 lt-ie8 lt-ie7" lang="en"> <![endif]--> <!--[if IE 7]> <html class="no-js lt-ie9 lt-ie8" lang="en"> <![endif]--> <!--[if IE 8]> <html class="no-js lt-ie9" lang="en"> <![endif]--> <!--[if gt IE 8]><!--> <html class="no-js" lang="en"> <!--<![endif]--> <head> <meta charset="utf-8"> <form class="form-search"> <input type="text" class="input-medium search-query" placeholder="Search by Tag"> <button type="submit" class="btn btn-primary">Search</button> </form>
