Boxes
Boxes are elements that are used to surround other elements, either to style them, to find them, or to place them in specific locations.
Wrapping elements in a box (see Boxes) or in a semantic HTML element makes it easier to target them in a script or a style sheet. Place the cursor in the element or select multiple elements. Then, on the menu, click Insert > Wrap in Box. You can now use the wrapper element as a script's or style's selector; see Using the Text Script Wizard and Styling and formatting.
Positioned Box
A Positioned Box is one that can be freely moved around
the page and does not depend on the position of other elements. A positioned box is actually a <div>
element that has an absolute position; in other words, it has its CSS property position set to absolute.
Positioned Boxes are suitable for use in Print templates only.
Adding a Positioned Box
To insert a Positioned Box, use the 
icon on the toolbar. Positioned Boxes can be moved
by dragging the borders, and resized using the handles on the sides and
the corners. They can be styled using the Format > Box menu item,
through the CTRL+M keyboard shortcut or through the CSS files; see Styling and formatting and Styling templates with CSS files.
Inline Box
An Inline Box is one that is placed within the text flow,
where other elements (including text) can wrap around it. An inline box
is actually a <div> element that is floating; in other words, it has its CSS property float set to left, right or no float.
Inline Boxes can be used in Print context and in Web pages. It is common to do entire web layouts using the float property. In Email templates, it is best to use Tables to position elements.
Adding an Inline Box
To insert an inline box, use the 
icon on the toolbar. Inline Boxes can be resized using the handles on the sides and corner. They can
be styled using the Format > Box menu item, through the CTRL+M keyboard
shortcut or through the CSS files; see Styling and formatting and Styling templates with CSS files.
Positioning an Inline Box
Initially an Inline Box will float to the left. Use the 
(Float left), 
(No float) and 
(Float right) icons on the toolbar to change the position of an Inline Box within the text.
- The Float leftbutton aligns the Inline Box to the left. The text is positioned to the right of it and is wrapped around the box.
- The Float rightbutton aligns the Inline Box to the right, with the text wrapped around it to the left.
- The No float button positions the Inline Box where it occurs in the text.
It is not possible to move an Inline Box using drag and drop. To move the Inline Box to another position in the text, you have to edit the HTML on the Source tab in the Workspace, moving the <div> element using cut and paste. To open the Source tab, click it (at the bottom of the Workspace) or select View > Source View.
Span
The Span element (<span> in HTML code) is used to group inline elements, such as text in a paragraph. A Span doesn't provide any visual change by itself, but it provides a way to target its content in a script or in a style sheet.
To wrap content in a span, select the text and other inline elements and click Insert > Wrap in Span on the menu. Give the span an ID, if you are going to add a style rule or script for it that is unique to this span; or give the span a class, if this span can be targeted by a style or script along with other pieces of content. Now you can use the wrapper's ID or class as a script's or style's selector; see Using the Text Script Wizard and Styling and formatting.
Div
The Div is the element used to create both Positioned Boxes and Inline Boxes. By default, a Div element reacts pretty much like a paragraph (<p>) or an inline box set to 'no float' except that it can be resized directly. Just like Positioned Boxes and Inline Boxes, Div elements can be styled using the Format > Box menu item, through the CTRL+M keyboard shortcut or through the CSS files; see Styling and formatting and Styling templates with CSS files.
Adding a Div element
To add a Div, select Insert > Structural Elements > Div on the menu. For an explanation of the options, see Inserting an element.
HTML tag: div, span
When you add elements, such as text, images or a table, to the content of a template, you are actually constructing an HTML file. It is possible to edit the source of the HTML file directly in the Designer; see Editing HTML.
In HTML, boxes are <div> elements. Spans are <span> elements. To learn how to change the attributes of elements, see Attributes.
