We need to identify each object in a web page by given a name to it. For example, the default name of a text box is Textbox1; if we insert another text box, the default name will be TextBox2. We can also change the names of the objects so that it is easier for us to identify them, like Txt_StudentName instead of just TextBox1.
Every object of a web page has many properties. The properties of an object reflect its characteristics or its behaviors. For example, the properties of a text box are name, height, width, background color, with a border or no border, font type and size and more.
We will learn how to write codes for the event handlers in later lessons.
