Hi All,

Could you please help to reduce the space between the head banner and the following section?

I have attached an image for your reference. The space between the yellow picture and the following section "Sourcing Inspection" is too wide. 

How to reduce the space?

Thanks a lot in advance for your kind help ! ^.^

Best,

JJ
