Historically, the functionality of the three primary scripts for coding web pages boiled down to creating the page's Basic structure with an Html document, applying styles to various aspects of that structure with CSS, and implementing interactive and animated elements through JavaScript. Thanks to updates applied to these and other coding languages over the past decade, it has become plausible for web developers to create basic yet striking animated and interactive effects with merely the first two scripts. It is easy for novice web designers to implement effects that react to page-scrolling motions and rollovers, and restricting these effects to HTML and CSS instead of using outdated formats like Flash files is a basic step in SEO.
A common approach to making a page feel less static is to have collapsible elements that are compact by default but individually expand and display descriptive text while the user's mouse cursor is hovering over each of them. One project page uploaded to codepen.io is an example that uses just HTML and CSS to portray a web page in which the user can hover over an image of one of several pizzas to establish and maintain its corresponding thumbnail. Though all the pizzas currently use the same stock image and placeholder text in this example, the concept is communicated effectively because of a smooth transition that invites the user to bring one Pizza to the forefront of their attention in order to read the content.
Each pizza's image is darkened but smoothly assumes a standard "brightness" parameter in the CSS while the user's cursor is highlighting it. At the same time, as the bottom edge of the box extends downward to create a second black box, the text that will fill out the new space smoothly materializes in terms of losing its transparency. Adding to the impact of the effect is that the text, the title above it, and the button beneath it also shift their positions relative to each other as they appear or disappear, giving the impression that the contents "expand from a contracted state" along with the black box itself.
