Dataset Card for CTXFont

Dataset Summary

CTXFont (Context Font) is a dataset for studying font selection in the context of web design. It contains 1,065 professional web designs from awwwards.com with annotations for 4,893 text elements. Each text element is annotated with font properties including font face, color (RGBA), and size, along with contextual information such as HTML tags, design tags, and element positioning. The dataset includes 492 unique font faces and provides 40-dimensional font face embeddings learned using an autoencoder. Web design screenshots are included at 768×1366 resolution.

The dataset was created for the task of predicting font properties (face, color, size) that match a given web design context, enabling automatic font selection systems that consider the visual and semantic context of the design.

The dataset is split into training (4,268 examples) and test (625 examples) sets.

Supported Tasks and Leaderboards

• Font Property Prediction: The dataset can be used to train models that predict font properties (font face, color, size) for text elements in web designs based on visual and semantic context. The original paper uses a multi-task deep neural network with adversarial learning.
• Font Face Prediction: Predict which font face best matches a given design context
• Font Color Prediction: Predict RGB color values for text that fits the design
• Font Size Prediction: Predict appropriate font size for text elements

No public leaderboard is currently available for this dataset.

Languages

The text content in the dataset is primarily in English, though the dataset focuses on visual and typographic properties rather than language modeling. Design tags and HTML tags are also in English.

Data Splits

The dataset is split into two sets:

	train	test
Examples	4,268	625

The split is based on unique web designs, ensuring that all text elements from the same design appear in the same split.

Dataset Creation

Curation Rationale

The dataset was created to enable research on context-aware font selection for web design. Traditional font selection tools model fonts in isolation without considering the visual and semantic context where they are used. This dataset enables the development of systems that can automatically suggest fonts that match the style, mood, and purpose of a given web design.

Source Data

The source data consists of professional web designs from awwwards.com, a platform where web designers submit their work for peer review and recognition.

Initial Data Collection and Normalization

The authors collected 1,065 web designs from awwwards.com, capturing screenshots at 768×1366 resolution (the most common screen resolution at the time). They automatically extracted font properties and text element information by parsing HTML source files. The dataset includes:

1. Screenshots of web designs
2. Annotations extracted from HTML/CSS: font face, size, color, position, HTML tags
3. Design tags provided by designers to describe the design characteristics
4. Font face embeddings learned using an autoencoder trained on 35,364 TrueType fonts

Not all fonts shown on webpages could be captured, as some may be embedded in images.

Who are the source language producers?

The source content was created by professional web designers who submitted their work to awwwards.com. These designers represent the global web design community and created the designs for various clients and purposes.

Annotations

The annotations consist of font properties and contextual information for text elements on web designs.

Annotation process

The annotations were automatically extracted from HTML and CSS source files of the web designs. For each text element visible on a webpage, the following were extracted:

• Font properties (face, color, size) from CSS
• HTML tag enclosing the text
• Position and bounding box from rendered layout
• Design tags were provided by the designers themselves when submitting to awwwards.com

Font face embeddings were computed using a separately trained autoencoder network.

Who are the annotators?

The annotations are machine-generated from HTML/CSS parsing. The design tags were provided by the original web designers who created the designs.
