To be precise, the submit buttons:
input type="submit". Very often designers want to somehow emphasize these buttons and are not very pleased with an answer “well, how about bold and colored caption?” :)
Recently, at the office, I had client request to create a design like this:
The HTML I had already was like this:
1 2 3 4 5 6 7 8
There was no chance to change this into anything drastically different as bunch of server-side code depended on form submit buttons being input elements. Thus, I went with this code and looked for CSS solutions.
One really helpful fact was that all captions were one line of code. Thus, I was able to use one long image with rounded corners. I had two nested elements as well, which is enough to get the design up.
