If you are keen to make or create your own website a good place to start is to check out some of casual gaming sites out there such as the sift head site as they usually designed with creative artwork which is integrated well using HTML. You will also want to acquire a basic knowledge both of web design and of SEO. You could sign up for a course taught at your local college or computer centre, but it is possible to learn these skills on your own as well.
To begin with, you need to familiarise yourself with the elements of web design. Go down to your local library and get out any books they might have on the subject. Use these in conjunction with information you get off the internet in order to give yourself a wide but well-grounded knowledge base.
Ideally, you need to get to grips with the basics of HTML coding. While this is not strictly necessary, it will give you more space to be flexible, versatile and creative in the long run.
You should also gain an understanding of the programmes which have supposedly rendered knowledge of coding obsolete. There are many of these but you will want to concentrate on two or three of the best known and most widely used.
Be sure to take advantage of internet tutorial sites which will calk you through both coding and programme use. Once you feel you mastered these two skills sufficiently, you will be ready to start thinking about building your site.
