For the design of a web application, the front-end developer offers one of his well-styled responsive themes , or makes a mockup using a professional design tool and designs the client part of the application based on of the model produced.

The interface made by the front-end developer must be compatible with all modern browsers
Modern browsers used to access the internet are plentiful, and you will never know which of these browsers people use to visit your website.
Take the example of a website that only looks good on the Firefox browser, and on other browsers it’s a disaster. This site will lose many visitors, suddenly it will have a very low traffic rate and it will be badly positioned by search engines.
Designing a website that is compatible with all modern browsers is the job of the front-end developer.
Do you see the importance of a job well done from the front-end developer?
Making a website compatible with different browsers is a huge and complex job. Front-end development requires knowing what browsers support, how to find and fix bugs and how to test your site on different browsers.
Today, modern browsers incorporate tools that require specific developments. This obliges the front-end developer to know these tools and study modern web technologies allowing him to carry out quality projects that meet the expectations of these tools.
Does your application interface display correctly on all terminals?
The front-end developer in addition to ensuring the compatibility of browsers, must also take into account the good display of his work on Desktop screens, tablets and especially smartphones.
He must work on the interface of his site so that it adapts perfectly and cleanly to the different terminals, that it has a perfect resolution for all the terminals and that deliver flexible content that resizes itself according to the different types of screens.
To do this, the front-end developer has the choice between a variety of libraries and frameworks to make a site responsive (a site that adapts to any medium).
Among all these sets of libraries, it is his responsibility to choose the best one, the one that is rich in components and features, and the most important is that it is regularly updated.
As an example, we can cite Twitter’s Bootstrap library that web giants such as Apple, Paypal, Slack use in their web application .
Did you know that the front-end developer is the bridge between visitors and the back-end developer?
The back-end developer sets up the algorithm making it possible to retrieve the elements requested by the user at the server level and to display them to him. But the user will not notice the work of the back-end developer if the front-end developer does not do an exceptional job.
Because the visitor sends a request, or performs an action via the interface set up by the front-end developer, so the latter must firstly encourage the user to take action with an attractive design of his interface.
And second, the result provided by the server must be presented properly so that the visitor can find it credible.
Here is a good illustrative example: for a visitor to an e-commerce site to grow curiosity to know more about a product, the presentation of this product must first of all arouse the desire for discovery. to the visitor.
And if the visitor likes the product, he will only enter his bank details to purchase this product if the proposed payment request form reassures him.
This example perfectly illustrates the importance of front-end development in web design.
Responsibility for good performance lies with the front-end developer
he front-end developer is responsible for the loading time of the contents, he is also responsible for the loaded contents and their optimization.
There are many reasons for the poor performance of a web application, they can be due to unoptimized visual content, heavy script files and stylesheets to load, or even certain extensions installed which slow down the loading of the site.
You will notice that all of the above items are tasks the front-end developer takes care of.
In order for visitors to receive the desired content in a short time, the web developer must play his role correctly by knowing how to properly optimize images for the web , and minify script files and style sheets.
If the site is performing well, the front-end developer satisfies both visitors and search engines.
