Let’s say we haveStartDate and EndDate and those are of type DateTime. If you want to have an int value as a result then: int theResult = (EndDate – StartDate).Days; And if you want to have a double value as a result then: double theResult = (EndDate – StartDate).TotalDays;
Let’s say you want to use 2 or more classes for a div. Then you should use these classes inside the class attribute, separated by whitespace: <div class=”myFirstClass mySecondClass”></div> To target elements that contain all of the specified classes, use this CSS selector (no space) in your CSS file: .myFirstClass.mySecondClass {}
