Not able to add padding to borders of CRM entity

Hello all,

I have 1 css file that is loaded on the start of the campaign page. We have applied border to the campaign sections.

//My CSS:

.ms-crm-FormSection {
border: 0.50px solid #ccc;

padding: 15px 15px 15px 5px;
}

Now I want to add padding left 5px but that is getting override with MS CRM css (something like read.css file) see img.

//MS CRM CSS

.refresh-form .ms-crm-FormBodyContainer
TABLE.ms-crm-FormSection {
padding: 15px 15px 15px 0px;
border-spacing: 0px;
}

So I am not able to give padding 5px even though I gave it in my CustomStylesheet.css file.

How to overcome it?
