Since weвЂ™ll do the content navigation by animating the panel wrapper, weвЂ™ll set the body overflow to hidden: This will make each panel be exactly the size of the screen (since the main container and the panel wrapper are) but allow an overflow of the content, stacking the panels in the classic way. But they will also have a width and height of 100%. Now, how do we make this layout flexible and its panels exactly the size of the screen? The trick is to make the main container absolute with a width and height of 100% while setting the panels and their wrapper to position relative. I know that it might be desirable to have the respective hashtag in the URL once we click on an input but with this technique that weвЂ™ll use for this layout it is not (yet) possible with CSS-only (parent selectors would be really nice to have!). The links have the href value of the panelsвЂ™ IDs, so for the fallback, weвЂ™ll simply hide the radio buttons, making the links clickable which will make it possible to вЂњjumpвЂќ to the right panel. The reason why we use links and not, like usually, labels, is that we want to be able to create some kind of вЂњfallbackвЂќ for non-supportive browsers (sibling combinators donвЂ™t work in older browsers). For being able to select the correct panel, we give IDs to them and to the radio buttons. Because of this technique, we need to keep the radio buttons in the same level like the st-scroll and on top of the links (they will be invisible though, since weвЂ™ll give them 0 opacity). This we can do by selecting the sibling of a checked radio button, the st-scroll division, with the sibling combinator and target the correct panel inside. What we want to do is basically move the panel wrapper by changing itвЂ™s top value and bringing the respective panel into the viewport. Each panel will have some content elements:Д«anksy adipisicing eiusmod banh mi sed. The structure will be consist of a main container with the class st-container which will contain the radio buttons and link, and the wrapper with the class st-scroll for the panels. You will, of course, find them in the files. Note that we will exclude vendor prefixes in this tutorial.

However, if you really wanted it to work in every browser, you could use javascript to make this work.Please note: the result of this tutorial will only work as intended in browsers that support the respective CSS properties. I consider this вЂњicingвЂќ and not necessary to the design, so I am okay with that difference. The transition will work in all of the latest versions of modern browsers, except Internet Explorer. You will also notice on the demo page, on the first menu, what happens when you put your transitions on the hover state вЂ“ the transition only occurs in one direction. By setting the height to 44px, the problem is solved. This problem is easily solved by giving a height to the parent of the anchor tags, which in this case is the вЂњliвЂќ tag. So the box size of the anchor tag (height + border, in this case) is not a static number. It appears that the transition of the border-size is not happening at exactly the same rate as the transition of the height.

If you look at the first two menus in the demo, both have a slight shift vertically when you hover over a menu item. Any of these values can be adjusted to personal design. The transition will occur on all properties that change (at least all properties that take a transition.) The easing is вЂњlinearвЂќ. The sliding up and down of the border will take place over. The transition is added with this part of the code:
