I have a lightning component which is going to be used for a Quick Action on a record page. I have implemented force:QuickActionWithoutHeader because I need to have custom "save" and "cancel" buttons. However, the modal that pops up for the quick action has a lot of excess white space, which makes the header and footer look out of place. How can I fix this?

Current Output:


Desired Output:
(Actually I would even like the modal pop-up to be smaller so that the input fields do not have so much excess white space, but if I can get the header and footer to look right I will settle for that)



Component Code:

<aura:component implements="force:lightningQuickActionWithoutHeader,flexipage:availableForRecordHome,force:hasRecordId" access="global" controller="FileUploadController">

    <div class="modal-header slds-modal__header slds-size_1-of-1">
        <h4 class="title slds-text-heading--medium" >Upload File</h4>
    </div>
        
        <!-- MODAL BODY / INPUT FORM -->    
    <div class="slds-modal__content slds-p-around--x-small slds-align_absolute-center slds-size_1-of-1 slds-is-relative" aura:id="modalbody" id="modalbody">
        <form class="slds-form--stacked">
            <!-- All the fields for the form input -->
       </form> 
  
    </div>   <!-- End of Modal Content -->  
        
        <!-- MODAL FOOTER -->
		<div class="modal-footer slds-modal__footer slds-size_1-of-1">
            <div class="forceChangeRecordTypeFooter">
                <ui:button class="slds-button slds-button_neutral" label="Cancel" press="{! c.cancel}" /> 
                <ui:button class="slds-button slds-button--brand"
                       label="Save" press="{!c.save}"/>
            </div>
        </div>
</aura:component>

 

I've gone to the Sales Executive Profile and set Read Only for Accounts and Opportunities Objects.  I even set a series of Sharing Rules for both Accounts and Opptys to view for everything created by both Inside Sales and Field Sales. 

Hi All,
I'm new to salesforce and started working on Trailhead's. I facing issue with the Trigger Challenge. Here is the triger code im writing 

trigger AccountAddressTrigger on Account (before insert) {
    for(Account a : Trigger.new){
        if(a.Match_Billing_Address__c && a.BillingPostalCode != null){
            a.ShippingPostalCode = a.BillingPostalCode;
        }
    }
    
}

but i'm getting the following error. Not sure where i'm doing wrong. can someone please help me here. Thanks in advance.

System.DmlException: Insert failed. First exception on row 0; first error: CANNOT_INSERT_UPDATE_ACTIVATE_ENTITY, TestTrigger: execution of AfterInsert caused by: System.NullPointerException: Attempt to de-reference a null object Trigger.TestTrigger: line 3, column 1: []
