I know it's not ideal, but if there's a 100% bitmap graphic header (with a text title rendered in the bitmap), the old way of making sure that there was a text counterpart to the graphic was to offset the text a few thousand pixels offscreen using CSS.
What's the current best practice for something like this? I know Google penalizes certain practices (like, for example, making text not display using certain techniques). Is there a way to do this in 2015 that's recommended?
Thanks!
