When you are just starting out as a website developer, it is important to give уоurѕеlf a lot of time fоr rеfеrеnсе and study. It іѕ nоt good to just thіnk аnd hope that you are gоіng to kеер up with all the updates іn the field.

You might be surprised to learn that there are quite a few mistakes that beginning web developers commonly make. Through this article, we hope that you can avoid them.

Being Dependent on Website Builder Tools

There are many website builder tools available today that make it easy for even beginners to build their own websites. Some of the more popular options include GoDaddy, Squarespace and Wix.

The problem with relying on these website builder tools is that these tools are not going to stay around forever. New website builder tools are constantly being released. At the same time, we also see tool providers disappear from the web design scene. In this case, you might be left with a website that no longer works with no way to fix it.

In addition, these website tools are going to force you to use their system exclusively. You are not going to have the flexibility that you want. Even if you might want to add some custom JavaScript or CSS to your website, the website builder tools will not allow you to do that.

Using Non-Responsive Design

When you are working on a website, you are going to have to consider the device that is being used to view the website. Mobile and tablet devices are becoming more popular, and you want to make sure that your website is going to work well on these devices.

The problem is that website builder tools were not built to be responsive. This means that you are not going to be able to take advantage of responsive features in these tools.

One way around this is to use a responsive framework. This is a tool that will help you build a responsive website from scratch with the skills that you have. This way you do not need to depend on any particular website builder tool.

Using Outdated HTML

All websites are built using HTML. So, it is important that you have a good handle on the fundamentals so that you can code your website properly. If you are using outdated HTML, then it will be harder to keep your website up to date.

This is one area where you might need to do some actual coding. You might have to be comfortable with HTML5 and CSS3. This will allow you to create websites that are responsive and adaptive.

You will also want to be able to handle HTML5 tags. These tags are going to be a better way to build a website. With this knowledge, you will also be able to handle HTML tags that were not around a few years back.

Cross-Browser Compatibility Issues

One of the biggest problems you will encounter as a developer is compatibility. If you are not careful, you might end up with a website that does not work properly on all devices. This can cause a lot of problems for your business and your clients.

One issue that is looming for many developers is the level of support for Flash. Some customers would rather not use Flash to view websites. So, you might want to avoid using Flash altogether.

You will want to make sure that you are not relying on any features that are outdated or no longer supported by certain browsers as they can cause compatibility issues.

Insufficient Input Validation

One of the most common issues that you will have to deal with when working in HTML is input validation. You will have to make sure that you have properly checked any user input to ensure that it is what you are expecting. If you are not careful, you could get unexpected input that could cause a lot of problems with your website.

Take your time to review the code on your website at least once a month. This way, you can also make sure that you are keeping it up to date with the latest versions of HTML and CSS. This can prevent you from having to make any big changes down the road.


In the end, it is important to remember that there is always room to improve. You are not going to be able to get everything exactly right the first time you make a website. So, take the time to study other websites and improve your skills.
