Front-end development gives structure and functionality to the external components of a website or web application. The principles of design and page structure are taken as reference points for making it both more attractive for the user, and usable. This is the main objective of the Front-end tasks carried out in the ROI UP Agency Digital Product Department.

Characteristics of correct Front-end development

Given our focus on the correct functioning of a site, here at the agency we take into account the different programming languages used and the specific functions of each. We can differentiate between three languages:

  • HTML: HyperText Markup Language. A key markup language which generates the structure of a webpage and can be used to organise content.
  • CSS: Cascading Style Sheets. This programming language relates to the styles of the webpage and its different formats.
  • JavaScript: this type of programming language makes language and styles interactive, since it can be interpreted by any browser in order to easily interact with CSS and HTML.

In the agency’s Digital Product Department, we effectively integrate these programming languages to give a website style and functionality, improving navigation and providing users with more options.
