i'm pretty new coding, bear me. i've got button on page that, if press on it, should make specific text bold.

but reason doesn't work , have no clue why..

here example:

html

<input type="button" class="btn" onclick="boldtext();" /> <br /> <div id="text">this text</div>

javascript

function boldtext () { document.getelementbyid('text').style.fontweight = 'bold'; }

my problem when click on button, nothing happens.
