My newest site redesign using WordPress as a Content Management System (CMS), is the website of professional Cleveland jazz musician Demetrius Steinmetz. Click the image below to visit.
One of the nice features about creating a website with WordPress is that it is responsive, meaning that it will resize/rearrange itself based on your screen size. If you are on a laptop or desktop, you can play around with this feature by grabbing the corner of your browser window and resizing it. As the window gets smaller, you should notice that the menu changes (becomes an expandable button), and the header image resizes accordingly.
My site, which you are on currently, is also a responsive WordPress site. You can test my site the same way, and as you resize the window, you should notice that the two-column layout becomes a one-column layout once the screen size is too narrow to accommodate two columns any longer (keep your eye on the sidebar where the blog posts are listed, as the screen shrinks, that block moves down to the bottom of the page).
