What is CMS without content to manage? Not much. That's why almost every content management system has an editor. In that editor you can type your texts, indicate what the headlines should be, where links should be, place images and so on. In short, create content. It's a bit similar to a text editor like Microsoft Word, so you can handle it in no time.
But you can customize other things too! With Pagewize, for example, you work with blocks. Blocks of text, photos, or whatever you want. You can fill each block yourself. Then you can also specify what you want it to look like. Large, small, square or round. With or without border and with or without background color. Pagewize even has a built-in photo editor! This way you can easily build your ideal website.
