CSS media queries
Learning web development is a journey an aspiring software engineer should consider, it involves learning, self-motivation and access to a lot of online resources, it’s also good to have a mentor.
Learning HTML & CSS is a great way to begin your web development journey but CSS media queries are like the icing on the cake referred to as the responsive web.
CSS media queries is a way of targeting devices, but it is helpful to know what the dimensions for all these devices are. They are the underlying theory of Responsive Design where we respond our content to fit any viewport.
Media queries are used together with flexbox to create a responsive website. It is also used to change many things as listed below:
a) the layout of a page depending on the orientation of the browser
b) it helps in making images and typography responsive
c) the width and height of the viewport and device.
A major component of responsive design is creating the right experience for the right device, with a gazillion different devices on the market, this can be a tall task.
There are various devices in the market as stated above, this means that using CSS media queries involves using different breakpoints. These breakpoints have different dimensions for different screen sizes.
Google defines breakpoints as the point at which the content of your site will respond to provide the user with the best possible layout to consume information.
For example, after designing a web page on a 17inches laptop screen, without media queries the web page will not be user friendly on the mobile view for obvious reasons.
It is pertinent for both web designers and developers, building a webpage to take responsiveness as a major key factor.
However, the breakpoints to be stated are usually the iPhone at 320px and 480px, the tablet (usually the iPad at 768px and 1024px) and finally anything above 1024px.
However, it is also recommended to design the mobile viewport first. Then, as you maximize the view, add the other breakpoints.

There are different ways of attaching the CSS media queries into your HTML file as listed below:
a) by adding it directly into your CSS file (use @media query)
b) directly add the media link tag into your HTML file
(use media=” tag within the header <link>)
c) by using Javascript to serve relevant CSS files
d) by using a mixture of all the above.
