EFFECTIVENESS OF CSS 3 OVER CONVENTIONAL JAVASCRIPT

When formatting or designing a website, many people are normally stuck as to which application is better between Cascading Style Sheets (CSS) and JavaScript. There are many factors to consider when choosing between CSS 3 and JavaScript but the issue of responsiveness should definitely be a major consideration when working on your web pages. First, it is important to note that CSS is designed to work with XML or HTML thus giving more control to web developers and users over their layouts including positioning, styling and display designing. The advantage is that CSS animations and snippets are basic and simpler as far as web page designing and styling is concerned. On the other hand, JavaScript is more complex and offers greater interactions and functions for web pages

Using CSS3 media query helps make your website responsive to all screen sizes as you create a flexible framework that allows images and text to shrink and adjust based on the browser and device being used. With responsive design, you can use media queries that give you a wide range of options allowing layouts including images, colors, and text and fonts styles to change depending on the size of the device screen in use. On the contrary, conventional JavaScript allows for more adaptive designs thus making it possible to design webpage at different sizes for different gadgets. This means that the web pages do not respond when loaded but instead detects the kind of device in use and loads the properly sized layout for view.

The conventional JavaScript animations are known to be quiet slow compared to the rather faster CSS3 animations. This makes the latter more advantageous for enhanced user-experience which translates to a better marketing campaign. Cascading Style Sheets have better hardware acceleration which can be broken down into two elements namely GPU involvement and the ability to use a special CPU thread for animation related calculations.

GPU is well optimized for various tasks such as applying transform matrices, moving pixels and opacity thus helping browsers to offload these tasks from CPU to GPU. This is done by isolating the animated components onto their individual GPU layers thus making it easy for the GPU to move the pixels around and merging them together, saving a large amount of pixels in form of layers. Using CSS3 snippets and animations helps the different browsers to verify the elements that should get GPU layers thus resizing and positioning them accordingly.

CSS3 offers a much easier learning language than conventional JavaScript thus offering an extra aesthetic to websites to make them more attractive and interactive. Additionally, CSS3 offers smaller codes which can be easily worked straight into the standard style sheets thus making it possible to browse without making too many HTTP requests. This also reduces the overall amount of loading time required to access web pages thus enhancing the speed in different devices. It is important to note that speed is a major factor when it comes to Google search ranking and this gives CSS3 and edge over conventional JavaScript especially in SEO campaigns. Google has adopted the use of site speed as a factor in algorithm ranking to encourage developers and designers to enhance user-experience online.
