If you are a web designer or a developer you might see a lot of units and values for different aspects of web design. For today’s web design, we need to convert most of the standard design units to different formats for flexibility. Exploration of smartphone industry pushes the website design industry to its best form. Designers and developers started thinking away from conventional web design methods. In early days, they have done different websites for different devices. It was not at all practical to build a web site for thousands of devices.
Responsive design is the ultimate solution for this complex situation. One website fit for all devices was the concept behind the responsive design and it was more about the layout. We have travelled far from the initial concept of responsive design. These days, there are many techniques used by developers to build and manipulate responsive websites. They are not just focusing too much to layout, but it covers the different elements to like images, fonts etc..
As these elements (fonts, Images, colour etc..) make a good website they need to have special care when you arrange them for different devices. Most of these laments controlled through certain values or units. If you are a developer, you need to have better understanding of these units and values to create an efficient website.
In this post, we have gathered an amazing list of converters and calculators for responsive design, color, typography, grid, pixel density. These handy tools are huge time savers and improve your workflow.
