What it takes

Hello all, I have really been loving the tutorials. I have really been able to apply this information into real world application. Now my current knowledge of html css javascript jquery is not the best i am starting to understand the essentials for a front end developer. Now, with that being said i have heard several answers to this questions and still have found any real clear understand standing but my question is this.

For a beginner level or entry level front end developer what are some the essential things that a developer should be able to perform. Now when i say perform i mean to successfully create such as a form with multiple fields, cool hover states/animations, succesful email submission and storing and using users inputed data and based off of users input deliver the site/webapp in a way that best suits there needs. these are things that I myself would for lack of a better term or word suffice to become or at least enter in to the realm of front end devleopment. I feel as if i am getting close to the piont to when i can truly call myself a developer.

As of now I work for a digital agency as a Quality Assurance Specialist. I had even had the chance to develop a press release for my company or in other create a fully responsive email. However though that is about the only code i have touched on a professional level. So again please iterate what you yourself feel are the basics or essentials for a basic entry level web developer. Thanks
