How to remove white space or keep the ROW alway on top

The reason that issue happens is the main content has it own padding top (usually 40px ) so in the ROW settings you need to decrease the margin top to remove the white space after header area.

Please do the following steps here:

1. Open your page edit with Elementor.
2. Open the first section setting.
3. Select the Advanced tab and set margin top is -40px or more.
4. Save and you’re done.
