Reduce Question Space

Hi Everyone

I am using this Java code in the 2nd question (text entry), to reduce the question space highlighted in red.

Qualtrics.SurveyEngine.addOnload(function()
{

	jQuery("#"+this.questionId+" .InputText").attr("placeholder", "Please provide detailed feedback.");
	jQuery('.QuestionText').eq(1).css('display','none');
	jQuery('.Separator').css('display','none');

I have also hidden the question text highlighted in red text using HTML.

<span style="visibility:hidden;">test</span>

How can I reduce this gap further?

Thanks :)
