Facebook & Javascript - Set textfield to hide by default

Hello all,

I can use the following code to hide a textfield as follows:

    document.getElementById('answerSequence').setStyle('display', 'none');

I can then show it again using the code below:

    document.getElementById('answerSequence').setStyle('display', '');


However, I want the textfield to be hidden when the page loads initially.  Any ideas how this may be done?

Many thanks, in advance, Colin.
