In the Content tab, you can choose a new content element and add it to your message. Just drag-and-drop a content element (for example, a button, an image, a text block, a transparent or solid divider, social media sharing widget, and so on) in the canvas area.
When you click a content element in the message, the Content Panel switches to Properties mode so you can change the settings of that particular element. If you click outside a content element, the row in which the content element is located is selected and its properties are available (for more information, see Drag and Drop Editor: Rows Tab).
The Content Properties area changes depending on the content element that has been selected. If you select a button, for example, you will see a number of tools to help you style the button and link it to your desired action (open a web page, send an email, make a phone call, and so on.)
In the example shown below, the ‘Show Me How’ button has been selected.
The properties panel switches to button mode and allows you to set the button’s width, background color, text color, alignment, the roundness of the corners, padding around the text, and much more!
With buttons as well as many other content items, the editor gives you complete control over the design of your email messages. Some of the controls, including content padding and borders, have both a simple editing mode (where only one Setting is shown) and an Advanced editing mode (where more control is provided, for example, specifying padding for the four sides of the object independently of each other.)
