About project

Trade-a-car is an e-commerce platform which I made for my design portfolio where consumers can buy and sell cars. The platform provides a user-friendly interface for customers to search and filter cars based on their preferences, such as make, model, year, and price range. The marketplace also provides detailed informations about the cars, including photos, descriptions, and technical specifications.The UI Design case study of this automotive marketplace focuses on the design process and the decisions made to create a seamless user experience for customers.


To understand the platform's target audience and the direction I should go with UI design, I created a persona. This helped me understand the needs, preferences and behaviors of my target audience and design a user interface that meets their needs.

The color palette is primarily composed of shades of blue and gray to give a professional and honest look. According to color theory blue represents trust, loyality and professionalism. Gray represents wisdom and dependability. Also it is generally believed that blue is one of the most universally liked colors across cultures and demographic groups.


As a typeface I used Poppins. As Google Fonts describes it “Poppins is one of the Geometric sans serif typefaces have been a popular design tool for building websites. Each letterform is nearly monolinear, with optical corrections applied to stroke joints where necessary to maintain an even typographic color.” It’s a very popular and aesthetically looking typeface.


For icons I chose available via Figma plugin called Iconify. As color for the icons I used bright blue and navy blue.


When designing the buttons I applied sharp corners to remain consistensy in design. Also I used sufficient contrast. According to WCAG 2.0 recommendations, the contrast ratio should be at least 4.5:1. For the buttons I used Space Grotesk typeface.


The logo I created is inspired by the logo on the Autotrader website. As for the color, I used the main blue.I considered few fonts for the logo but finally I decided to use Dela Gothic One.

Grid and alignment

For the desktop frame I used default width of 1440px. As for the grid, I applied a common settings of 12 columns, 140 px margins, 30 px gutter.

Low Fidelity Wireframes

After finalizing the Low Fidelity design, I had a better understanding of what the website should look like.
