Responsive Web Design uses the following technologies
- Fluid, proportion based grids – This concept enables the web page elements to be sized in relative units such as – percentage rather than absolute units like pixels.
- Flexible images – The size of the images is also in relative units like percentage which allows them not to come out of their containing elements.
- HTML5 – Websites built using Responsive Web Design are written in HTML5 markup language. HTML5 is popular for structuring and presenting content on the internet.
- CSS3 media queries – With various CSS (Cascade style sheets) media queries the width of the website can be easily varied in different devices. The website adjusts itself automatically in a mobile device or a PC.
The combination of all these concepts in Responsive Web Design, make it possible to adapt the layout to the viewing environment.
To make it easier to understand we can say that Responsive Web Development is a technique to make web designs which provide the user with the best viewing experience. These web designs are quite interactive and offer an excellent UI/UX interface. Websites built using RWD provide user friendly navigation and as already discussed, they can be viewed in a wide range of devices (from desktop to mobile). Just as fluids take up the shape of the container they are placed in similarly websites built using Responsive Web Design take the shape of the device they are browsed in.
As mobile internet use accounts for more than half of the internet use hence Responsive Web Development has become a very popular technology in recent times. In fact, Google increases the rating of a website, if it has a mobile friendly design.
All popular website you come across with, are built using HTML5 and CSS3 media queries. CSS3 media queries form a very important part of RWD. So let us try to understand CSS3 more clearly.
CSS3 And Its Features
An important feature of CSS is that it allows the current .css file to be overridden easily. Hence, changes can be easily made to a hundred of documents by simply editing a few lines in the CSS files. Inheritance is another feature of CSS which in a style sheet prevents certain properties from being declared again and again. This allows software developers to write less CSS and enables faster loading of web pages. A lot of money which goes into development cost is also saved with this feature. CSS also uses techniques such as CSS hacks to target all types of browsers.
CSS, over the years has gradually updated from CSS1, CSS2, and CSS2.1 to CSS3. Each time a new version is launched it has added features as compared to its previous version. Such an added feature in CSS3 is column-count module which allows implementation of layouts with multiple columns easier. At Micro Pyramid we ensure Responsive Web Development is done using HTML5 and CSS3.
CSS3 Media Queries
CSS3 media queries are an extremely important technology in Responsive Web Development. The media queries in the CSS module allow content rendering to adapt to conditions such as screen resolution. (For eg – Smartphone screen Vs Computer screen)
CSS is written in dynamic style sheet languages, Saas and less. Less is inspired by Saas and is simply an extended form of CSS. (For eg- The curly brackets used while writing the syntax in CSS was removed from less) Newer Saas versions have also introduced CSS like syntaxes such as SCSS (Sassy CSS).
Both of these CSS pre-processors have many features, such as –
- They allow variables to be defined easily.
- They allow nesting.
- They allow efficient code repetition.
CSS Frameworks (Bootstrap and Foundation)
There are also some pre-defined libraries of CSS frameworks available which make styling web pages much easier. They offer readymade options for designing and layout. Two of such frameworks are Bootstrap and Foundation.
