# WAFFLE: Multi-Modal Model for Automated Front-End Development
We develope WAFFLE, a fine-tuning approach to train multi-modal LLM (MLLM) to generate HTML code from webpage screenshots or UI designs. WAFFLE uses a structure-aware attention mechanism to improve MLLMs' understanding of HTML's structure and a contrastive fine-tuning approach to align MLLMs' understanding of UI images and HTML code. Models fine-tuned with WAFFLE show up to 9.00 pp (percentage point) higher HTML match, 0.0982 higher CW-SSIM, 32.99 higher CLIP, and 27.12 pp higher LLEM on our new benchmark WebSight-Test and an existing benchmark Design2Code.

## Structure
- `vlm_websight` contains the dataset class file, model class files, and training file for vlm_websight.
    - `eval_websight.py` is the inference file
    - `dataset.py` is the dataset class file
- WebSight-Test is one of our test dataset

## Quick Start
```bash
cd vlm_websight
# generate HTML/CSS code for UI image --image_path, save the code to --html_path
python quick_start.py --image_path ../WebSight-Test/test-495.png --html_path examples/example-495.html
# render the HTML/CSS code in --html_path, and save the rendered image to --image_path
python render_html.py --html_path examples/example-495.html --image_path examples/example-495.png
```
