I am looking to build a really simple (info only) website for a primary school. Some of the example websites I've seen for primary schools are often bright, colorful and contain almost a cartoony feel to it. Could you please tell me what is used to create these designs is it just photoshop built from scratch or are these graphics brought from somewhere. Thanks

Thank you for your replies!

I am looking to get back into i.t after a career break. I did computer science at uni and worked for one of the big 5. I have decided to pursue web design and am tinkering with HTML, CSS and wordpress. I understand I need to build up a portfolio and have approached my local primary school because they have an outdated website. I suggested a couple of improvements that could be done and I said that if they want in the short term I could maintain their existing website on a voluntary basis as the person who does it does not get time to update it and parents want upto date info on it. In the long term I would like to offer to redo their website once I'm more proficient but wanted to know whether : you thought wordpress would be suitable for a school website or if not what would you suggest. Also, to create mock up designs for a website to show to the client what would you use?
