Christine - yes, absolutely, and that was what I tried to do. But I have a geocities website (I am not a web-designer or anything even remotely clever) and that has some limitations.
I can use "buttons" that look like buttons - but when they are placed alongside the text within the frame they float - and they do not show on the finished page in the correct place. The only way I could get a link that worked given my limitations, was to use some form of type/letter/symbol. That gives further problems, because some symbols do not show up the same on computers around the world (I know, as I have used the Copyright symbol that appears fine on my computer, but a friend in the US sees it as an entirely different symbol.
So - I experimented with a variety of numbers, symbols etc. And the combination I finally used seemed to work (and look) the best in the circumstances.
I guess I will never please everybody. So in the end I just have to do the best within my capabilities and give everyone the opportunity to access as much information as possible, as easily as possible.
BTW adding those buttons and links since yesterday has taken up around 8 hours of my time, so I'm not in a hurry to alter anything. My apologies to anyone who has any difficulty using my website.
