Hi Deepali are you considering to use Mendix 8? We introduce the design patterns in the 'Appearance tab' that gives you CSS classes out-of-the-box :)

I believe you should have a look at the margins and paddings.
In MX, double click the element, there's “styles” section and you can add some custom CSS.
