HTML5 Figure Element
The <figure> element should be used to insert images since it has a <figcaption> element for inserting the caption. An image without alt text and a caption may as well not be there as far as the search engines are concerned. When a <figure> element is used, the search engines know that the text in the <figcaption> is related to the image.
The caption can be inserted below the image as shown in the first example or it can overlay the image as shown above, The overlay position can be top or bottom and there is a control to adjust iys position on th Y-axis.
The caption can use a web safe font or a non-web safe font or Google hosted font with a web safe fallback, There are controls for font size, color, padding and background color and its opacity.
When positioned below the image, the caption background control is not required since the exposed area containing the caption will have the color set by the control for the containerbackground.
Links
