How many websites use Pure CSS?

We track 14,751 websites that use Pure CSS in 2026. Those sites span 45 industries and 33 countries. The crawler re-checks each domain daily. So the count moves as sites adopt Pure CSS or drop it.

Pure CSS belongs to the UI frameworks category. Sites in that category tend to share a similar stack. As a result, they often share buying patterns too.

The table above shows a sample of 100 matched companies. Each row carries an industry, a country, and a live domain. You can search it, sort it, and export it.

Which industries use Pure CSS most?

Adoption is not spread evenly. Instead, a few industries account for most of the matched sample:

Information Services8%
Retail7.000000000000001%
Information Technology and Services6%
Marketing Services4%
Financial Services4%

Information Services leads that list. However, the long tail matters just as much. Adoption reaches 45 industries in total. So you can narrow the list to the segment you sell into.

Where are websites that use Pure CSS based?

The matched companies sit in 33 countries. These lead the sample:

United States 36
United Kingdom 9
Brazil 6
Spain 5
Australia 4

United States is the largest single market in this sample. Because the country is stored per row, you can filter before you export. That keeps your outreach inside one timezone and one legal regime.

How to find websites that use Pure CSS

Start with the table above. Then follow these four steps to turn it into an outreach list:

Filter the sample. Narrow by industry or country until the rows match your ideal customer profile.
Export the domains. Share the page to unlock the CSV, or sign in for the full dataset.
Find the people. Run each domain through Domain Search to pull every work email behind it.
Verify before you send. Pass the results through the Email Verifier so your bounce rate stays low.

Working at volume? Push the whole export through Bulk Tasks instead, or call the Domain Search API directly from your own stack.

Frequently asked questions

How fresh is the Pure CSS data?

Our crawler re-checks technology signals daily. So a site that removes Pure CSS drops out of the index, and a new adopter appears without you refreshing anything.

Yes. Every domain in the table can be enriched with verified work emails and direct phone numbers. Run a single domain through Domain Search, or push the whole export through Bulk Tasks.
