Scroll to top or Back To Top Button for website


Scroll to top or Back To Top Button for website




This "Back to top" link allows users to smoothly scroll back to the top of the page. It's a little detail which enhances navigation experience on website with long pages.











This resource is suitable for website with lots of page content. The link fades in on the right-hand side of the content area, after the browser window has been scrolled beyond a certain point, and remains fixed during scrolling.

If users keeps on scrolling, the button nicely reduces its opacity to be less distracting during navigation.




Creating the structure




We inserted the “Back to top” link at the bottom of our content, before the closing tag.




<body>
	<!-- all your content here -->
 
	<a href="#0" class="cd-top">Top</a>
 
	<!-- link to scripts here -->
</body>




Adding style




The link will appear fixed on the right-side of the content. Initially it has a visibility:hidden;

 and an opacity:0;.

Both visibility and opacity are controlled through two classes: .cd-is-visible and .cd-fade-out.




.cd-top.cd-is-visible {
  /* the button becomes visible */
  visibility: visible;
  opacity: 1;
}
.cd-top.cd-fade-out {
  /* if the user keeps scrolling down, the button is out of focus and becomes less visible */
  opacity: .5;
}




These classes are added (or removed) to the “Back to top” link using jQuery.




Events handling




In our .js file, we have defined three variables to control the “Back to top” link appearance:



//browser window scroll (in pixels) after which the "back to top" link is shown
var offset = 300,
	//browser window scroll (in pixels) after which the "back to top" link opacity is reduced
	offset_opacity = 1200,
	//duration of the top scrolling animation (in ms)
	scroll_top_duration = 700;




The offset variable will be used to toggle the class .cd-is-visible; the offset_opacity, instead, to add the .cd-fade-out class.

The top scrolling function is implemented using the jQuery .animate() method, and bound to the “Back to top” click event.

Bouncy Content Filter for big Website

This space-saving content filter allows the users to switch from one category to the other in a fancy way! Each click fires the rotation of the gallery images, revealing the items belonging to the selected category. Content filters  are particularly useful for big websites, where each pixel counts. Lets say you are showing the “ last products ” of your e-commerce . How about giving the users the option to switch to the “most popular” products without a page refresh? A good solution could be to hide the “most popular” items right behind the “last products”, then use the power of CSS3 3D Transforms to rotate the items when the user switches from one option to the other. The bounce effect is optional, but you get the idea! The rotation won’t work on older browsers like IE9, but the experience won’t be broken – just a display on/off with no transitions. Lets dive into the code! Creating the structure We wrapped the filter into a <nav> element. The filter structur...

Content slider with Zoom Effect for a predefined area in each slide

Zoom Slider Today’s Blueprint is a simple content slider with depth-like zoom functionality. Each slide has a predefined zoom area that will be used to calculate the appropriate scale value for a fullscreen fill. Once the icon for zooming is clicked, the zoom area as well as the page get scaled, creating the illusion that the viewer is approaching the item. Once the whole page is covered, we show some more details. Navigating the slider will animate the inner parts of the slide, allowing for an independent control of the image area and the title. We are using CSS transitions and dymanic.js for moving the slide elements. Dymanic.js by Michaël Villar is a JavaScript library to create physics-based animations. Please note that we are using a couple of modern CSS properties, so only contemporary browsers are supported. The HTML <!-- Main container --> <div class="container"> <!-- Blueprint header --> <header class="bp-header cf"> ...
