Once the page has been created, we can add controls to it.
Controls in the sense of what functional item you want to put on your page. They are the elements that you want to see on the wireframe that’s being created. There are a lot of controls that are available to make the creation of a webpage tidy.
These elements all together makes the webpage as a whole.
Let's say, you want to add a button saying Click me! in the center of a browser window. So to achieve this, you have to add two controls
1. Browser control
2. Button control
Navigate to the Controls section in the side menu bar. This shows you a list of controls. You can either click on the control you want or drag the control to the canvas section. The control is now added to the page.
