I like the idea of handle alignment transparently (mapping it into different styles under the hood), probably this thing should be done in a separate plugin to be properly reused in all different dialogs. I considered that a feature lost, vertical-align is still very critical for text surround images/objects.Īlign "center" is still a very useful option, for iframes but also for tables. No vertical alignment should be considered at this moment. When loading an image with the "align" attribute, we should remove it only if it matches "left" or "right", otherwise we just leave it intact. So, for now, we could reduce the number of alignment options to "Left" and "Right" only. For the eyes of end users, we're always talking about "Align". The value yes gives scrollbars at all times, and the value no suppresses scrollbars-even when they are needed to see all the content.We should not have two separated options "Align" and "Float". The default value, auto, generates scrollbars only when necessary.
The SCROLLING attribute specifies whether scrollbars are provided for the inline frame. The value must be a non-negative integer. The MARGINWIDTH and MARGINHEIGHT attributes define the number of pixels to use as the left/right margins and top/bottom margins, respectively, within the inline frame. The vertical-align and float properties of Cascading Style Sheets provide more flexible methods of aligning inline frames. To place content below the frame, use as appropriate. The other ALIGN values, left and right, specify a floating frame the frame is placed at the left or right margin and content flows around it. To center the frame horizontally on the page, place the frame in a centered block, e.g., The values top, middle, and bottom specify the frame's position with respect to surrounding content on its left and right.ĪLIGN=middle aligns the vertical center of the frame with the current baseline. The ALIGN attribute specifies the alignment of the inline frame. Style sheets allow greater flexibility in suggesting the border presentation. The default value of 1 results in a border while a value of 0 suppresses the border. The FRAMEBORDER attribute specifies whether or not a border should be drawn. The WIDTH and HEIGHT attributes specify the dimensions of the inline frame in pixels or as a percentage of the available space.
Note that LONGDESC describes the frame content while the content of the IFRAME element acts as a replacement when the external resource cannot be inlined.

This is particularly useful for full descriptions of embedded objects.
The LONGDESC attribute gives the URI of a long description of the frame's contents. For example, an IFRAME within an H1 cannot contain an H2, but an IFRAME within a DIV can contain any block-level elements. The content may consist of inline or block-level elements, though any block-level elements must be allowed inside the containing element of IFRAME. The content of the IFRAME element is used as an alternative for browsers that are not configured to show or do not support inline frames. The optional NAME attribute specifies the name of the inline frame, allowing links to target the frame. IFRAME's SRC attribute provides the location of the frame content-typically an HTML document. However, OBJECT is included in HTML 4 Strict while IFRAME is not. One advantage of IFRAME is that it can act as a target for other links. IFRAME provides similar functionality to OBJECT. The IFRAME element defines an inline frame for the inclusion of external objects including other HTML documents.
