I have like 10 aspx pages (junior_class_students1.aspx-...10.aspx). They all have the same master page in the back (class_students.master). Everytime i load a page i want the master page background-color to change, to the one that i can specify per page. so ...students1.aspx then .master ...students2.aspx then .master ...students3.aspx then .master how can this be achieved?
