How can you apply CSS style using ID value?

A CSS ID  selector uses the ID attribute to select one unique element on apage of an HTML. 

To use an ID value , write a hashtag(#) followed by the ID of the element. The in the brackets add the style properties that you want to apply th the element.

( This knowledge I gathered from the Internet)

I HAVE NO EXPERIENCE IN THIS. I WILL TRY TO GET THE INFORMATION AND PROVIDE SAME,

You can create the style using the # key selector with the ID name then apply the CSS Value to the paragraph Tag.

#idname

{

style You wanted to apply

}
