# Block Resources

> Source: https://scrape.do/documentation/headless-browser/block-resources/

Optimize performance by blocking CSS and images

By default, this feature is enabled so that results are loaded faster and returned to you more quickly when you navigate to a website through the headless browser. CSS files, images, and fonts are blocked to improve performance and reduce bandwidth usage.

If you want to turn this feature off, simply pass the `blockResources=false` parameter.

> [!NOTE]
> This feature may affect success rates for some target websites. Therefore, setting **false** on problematic web pages may increase your success rate if the site requires images or CSS to load properly.

```bash
curl --location --request GET 'https://api.scrape.do/?url=https://httpbin.co/anything&render=True&token=YOUR_TOKEN&blockResources=false'
```

**Python (API mode)**

```python
import requests
import urllib.parse

url = "http://api.scrape.do/?token={}&url={}&render={}&blockResources={}".format(token, targetUrl,render,blockResources)
response = requests.request("GET", url)
print(response.text)
```

**Node.js (API mode)**
