Front end developers are given the responsibility to create and develop everything which will be seen by the users of the site and interact with. This is including creating interfaces and bringing to life that are engaging and aesthetically pleasing to viewers. It also means that if a user interface is working well then it will be a success. The wrong design can crush a websites revenue, reduce the user base and hence getting the design right is the role of a front-end developer.

In front-end development, it’s very important to understand users and their behaviors to build a beautifully functioning front-end, but there are also a few common coding mistakes to avoid. Here are some common coding mistakes which you should avoid at all costs:

Using Tables Instead of Div Containers

As a Web Development Company in Navi Mumbai, tables were the de-facto way of HTML element design in the past, when it was deprecated the use of div tags came into effect and CSS were used to design into the front-end of the website. Tables can be pretty messy and can cause design flaws and misplacements in different browsers.

Tables have been replaced by div containers and CSS stylesheets which can be used for optimal placements of elements and create a layout. Tables are still useful when displaying charts of information, but they’re rarely used to create layouts.

Coding with Old HTML Elements

HTML5 is the newest form of HTML coding language, includes many awesome changes to your site and it provides a lot of changes to the standard page design. HTML5 replaces elements such as Adobe Flash with the canvas tag. The new standards also deprecated some tags such as frames and center of CSS design.

It’s usually best to avoid coding with older HTML standards. Front-end design depends heavily on browser support. Older HTML support is not always available in some browsers, and it’s bad practice that can put your site at a disadvantage in the long run. The code can be harder to support and in some cases, it can leave your site more vulnerable to security attacks.

Not Testing for Each Major Browser

As a Website Development Company in Mumbai, front end design relies heavily on Javascript and client-side scripting. Hence, it is important that you test all major browsers. At a minimum, users will want to test for the Chrome, Mozilla and Microsoft browsers. You can determine which browsers you would like to support by looking at your site’s browsing analytics data or using an external source to determine common browsers.

You should also calculate which the oldest browser you would like to support us. Many user’s stick with older browsers as their computer ages, so you should weigh the pros and cons of possibly alienating these users with the effort it takes to maintain code for both older and newer browsers. Decide the oldest browser version you’ll support and then test on these older versions.

Forgetting Responsive Mobile Design

Mobile is the next generation of web browsing. Tablets and smartphones are the most popular ways for browsing the web, increasingly replacing desktop browsing. Your front end design should always support mobile browsing otherwise you risk the search engine results penalties. You can also create a separate site for mobile on a subdomain, but responsive design should be the default in modern front-end coding.

After creating a mobile, responsive design, you should also test it on various browsers and browser versions. Mobile devices have several different screen sizes, so ensure that your code supports all possible breakpoints.

Not Prioritizing Site Speed

Server and bandwidth are important for the speed of the site, but there can be a bloated front end which could affect even the fastest server. Image size is a major factor, as is the bloated JavaScript code that could be too slow. One way is to streamline the JavaScript code and reduce the image size on the website. Always reduce image size and use a format that can be resized without losing much quality.

Several site speed testers are available to help you identify what elements of your site design are slowing down your application. As with responsive design, search engines take site speed into consideration for ranking. A best practice would be to always test your site and ensure its performance is fine tuned.

Being Outdated or Abandoned JavaScript Libraries

Stick to JavaScript libraries which have been updated, have active support and documentation. You do not need to choose libraries which are world famous, but choose libraries which will be maintained down the line. If the library is not supported or maintained years later, you might find yourself in a sticky situation with a dependency that is no longer functional if a developer abandons his or her project.

It’s difficult to predict which libraries a developer will choose from, or what he will do with a project years from now, but you can view its popularity by searching the number of support communities online. You can’t go wrong with AngularJS or Knockout libraries- they’re popular and supported by big brands.
