To be able to understand more about web design, you should start by understanding different types of the design first.
Fixed web design: A fixed web page is the set of the width which is never going to change if the browser has to be resized regardless of the website that it is being used in viewing this. The content is hard to be viewed when it is being read on the tablets or smartphones. The user gets annoyed if they have to view the content only after scrolling horizontally in order to view what it is on the content. If the browser and the screen is being reduced or enlarged, the text can fall apart at the screen.
Fluid or liquid design: when the browser is resized, content in the page will spread itself to fill into the width of a browser if it is expended. This is where the term liquid design came from since the website may look enlarged at one device or shrunk at the others. The columns that have the content at the webpage are being built with the percentage in mind but not the columns that have been fixed. The columns can decrease or increase according to a device.
Responsive design: the approach makes it easy for the website to be viewed on any devices in the form that it is easy to navigate or to read. This means that the user will not have to resize, scroll or pan anything while reading the content of the website. The website can be viewed easily on the smartphones, tablets, computers and the desktop. When it comes to creating the responsive website, the designers will not have to design the multiple websites so that they can fit different devices.
The website where the responsive design had been used, they can be designed for displaying many content since the browser may expand or may reduce to reach to the predetermined size. The example may be if a certain website is reduced to reach up to 70 percent of the maximum width, only two different columns are going to be found at the screen.
The images and video quality can also be different depending on the connection of the internet which the device is using. For example, a video that was downloaded has high quality compared to the video that it has to be watched using slow connection since uploaded video has high resolution compared to the one being watched at a slow connection. Low quality video means that the video will be downloaded faster compared to the buffering screen of high quality version.
Before any company decides on which type of the web design to use, they should consider the target audience and the devices that they are viewing their websites on. The example can be when the audience does not use the smartphones; there is no need to work on the responsive design that will fit smartphones. If you think that in the near future the audience may use the smartphones to be ahead, you will have to prepare the website so that it can fit every device.
