A second tap on the parent link will navigate to that URL. In the demo below you can see a centered menu, hover over the top-level menu items and a submenu will dropdown below each one.įor touch devices like iPhones and iPads, you simply tap to open each submenu.
iPhone & iPod Touchĭemo: Centered Menu With Dropdowns (submenus) The pure CSS-centered menus have been tested on the following browsers. Some website layouts rely on JavaScript hacks to resize divs and force elements into place but you won't see any of that nonsense here.
It is becoming increasingly more important to make your website resizable text compatible because people are expecting higher levels of web accessibility. People who are vision impaired can make the text larger so it's easier for them to read. Resizable text is important for web accessibility. These centered tabs are fully compatible with resizable text. The HTML in these centered menus validates as XHTML 1.0 strict. Instead, this design uses clever relative positioning. To overcome Internet Explorer's broken box model, no horizontal padding or margins are used. The CSS used for these centered menus is 100% valid and hack-free.

Download my demo files so you can play with them yourself. The following centered menus all use the same HTML markup, only their CSS is different. Here's the completed CSS: div#centeredmenu but these are not supported in old versions of Internet Explorer. This will be 50% of the width of the parent ul element and will put the menu exactly in the center of the window. The last step is to shift the li elements back to the right by 50% with position:relative and left:50%. Shift the line items to the right (green 'li') Now our menu is partly cut-off by the left of the screen, but don't worry, in one more step, we will have it in the center. So in this instance, the ul element will move to the left by 50% of the parent div width (half of the browser viewport). Important note: When moving an element to the side by a percentage value, the distance will be a percentage of its containing element's width, not its width. Next, we shift the ul element to the left by 50% by using position:relative and right:50%. Shift the unordered list to the left (magenta 'ul')

The links are set to display:block so the full rectangle is clickable. The li elements are all floated to the left so they line up horizontally. The ul is floated to the right side of the page and it shrinks to the size of the menu. To prevent the div from shrinking horizontally I added width:100% so it stays the full width of the page. The outer div is floated so it stretches down to contain the ul inside it. We start with a standard right-aligned menu: Each element type is a different color so it's easy to see the menu structureĪ right-aligned menu is styled in the following way: The container (blue 'div') The structure is simply a list of links in a single div. The HTML used for these centered menus is semantically correct and very basic. So, now we understand how floats work, let's look at the HTML structure of a centered menu Step 2. This shrinking of floated elements is the key to the centering process, it helps us move our menu the right distance to the center. In the illustration above, the floated div is now only as wide as the text 'div' inside it. If we float the div to the left or right (it doesn't matter which direction) the div will automatically shrink to match the width of the content inside itself. Notice how it automatically stretches to 100% of the width of its containing element (the browser viewport). Here is a simple blue div that is not floated. To explain this properly let me first describe how an element can change its dimensions when floated. The trick to my centering method is how the floated elements are relatively positioned within one another. Understand the key principle: Floated elements shrink to the width of their contents Let's see how centered menus work step-by-step so you can create them for yourself. At the end of this article, I have some nice centered menu examples. Of course, we could make much a nicer design but this will do for now.
