Responsive web design (RWD) is an approach to web design that makes web pages render well on a variety of devices and window or screen sizes. Content, design and performance are necessary across all devices to ensure usability and satisfaction. A website designed with RWD adapts the layout to the viewing environment by using fluid, proportion-based grids, flexible images, and CSS3 media queries.
The fluid grid concept calls for page element sizing to be in relative units like percentages, rather than absolute units like pixels or points. Flexible images are also sized in relative units, to prevent them from displaying outside their containing element. Media queries allow the page to use different CSS style rules based on characteristics of the device the site is being displayed on, e.g. width of the browser window width or display size. Responsive web design has become more important as the amount of mobile traffic has come to account for more than half of total internet traffic.
Responsive navbars are increasingly important to have as mobile web browsing becomes more popular, and they are surprisingly easy to create with CSS techniques.

CSS Grids make it easier to create website layouts. Using grids simplifies both your HTML and CSS, while giving you more control over your layout.
CSS custom properties bring the power of variables to CSS, which results in less repetition, better readability, and more flexibility.
Website developers are responsible for both the graphical aspects of website design, as well as technical requirements including performance and capacity. In addition, either Android app development or iOS apps may be called for as an adjunct to mobile websites. Beyond a thorough background in HTML5 and CSS, webmasters must master JavaScript and PHP/mySQL. The minimum education needed to become a website designer is an associate's degree or certificate, although many software engineers have an EECS degree or a bachelors degree in computer science. The average annual wage for web developers was $64,970 in May 2017.
