Image captions are an often-overlooked element of Web design. They’re often thought of more in terms of function than form. As long as they include the proper photo credits or identifying information about the image subject, not much more thought is given to them.
But image captions are a great place to add a bit more style to your website or to give some unique insight into the subject of the image. Whether the captions are for photos on a news website or design samples in a portfolio, they present an opportunity for reinforcing the overall look of the website. When done properly, they can even add more visual interest and become a distinguishing trademark of a particular brand or website.
There are two basic kinds of photo captions. There is the simple, minimalist, down-to-business style. These usually have a simple sans-serif font in white, black or shades of gray. They are usually positioned either to the side or below an image, though sometimes they overlay or are above it. This type is commonly found on news websites but is also seen in portfolios and other websites.
The other major style is more graphic. This often include effects, such as the caption only appearing on a mouse-over or a “Details” button displayed that leads to the full caption. While fonts are still generally sans-serif, much more color is used, and the captions are often overlaid on the actual image. These types of image captions are generally seen on portfolio websites of designers and ad agencies. Of course, there are websites that use a crossover-type image caption, displaying elements of both styles.
