Hi, I’m Shapeshifter 3! TOOLBOX-4-WEBSITES is based upon Mobile First web design. Using the cursor of your mouse, drag the right edge of the window towards the left. Notice that the display vertically stacks the content, until you reach the screen size of most smart phones. If you have one, try that on your own website. Is any of your Content, Header, Images, Menus, or Text jammed together or missing? Is it difficult or time consuming to browse your site on mobile devices? If so, your viewers may just move on elsewhere. Depending upon the purpose of your site, that may or may not matter. If it does, UPDATE OR SWITCH YOUR BROWSER , start your own educational journey here, and then possibly redesign your own website. If you don’t have one, try out one of the builders on my homepage. (Not interested? Try out one of these instead: MUSIC VIDEOS ).
