color Text Field in Appian v1 7.3

Question

Hi everyone, I saw in Appain 17.3 Release Note a box layout, 
 where I found a RED color Text Field inside the box component, 
 do you know the expression to do so?

In that case you can use a!richTextItem() sail component. Pass in "NEGATIVE" to the "style" parameter.

joanneh , That is a!richTextDisplayField(). Inside that they I have used a!richTextItem() with style 'Negative'. Below is the sample snippet. 
 
a!richTextDisplayField( 
 value:a!richTextItem( 
 text:"Hi", 
 style:"NEGATIVE" 
 ) 
) 
 
Hope it will help your query...!!!

You can use the new a!boxLayout() sail component. The "Style" parameter determines the color of the text. In your case, you would use "ERROR" for red text. 
 IE: 
 a!boxLayout( 
 label: "Sorry! There was a problem with your order", 
 style: " ERROR ", 
 contents: { 
 a!textField( 
 labelPosition: "COLLAPSED", 
 value: "Your credit card could not be charged.", 
 readOnly: true 
 ) 
 } 
 )
