Is there any site that collects some UIs at least HTML/CSS?
For example:
- Search UI with filters
- Product Designer (drag & drop elements)
- Typical Grid/List switcher
- Map with filters
There are tons of very reasonable priced UI kits that come with all the bells & whistles on <a href="https://themeforest.net" rel="nofollow">https://themeforest.net</a>. I've used it a few times for side projects and such when I'm just trying to put something together fast. For $30 you have a killer UI, HTML, CSS/SCSS, and JS. That's obviously a paid route. For free, I'd go with something like Bootstrap, Foundation, or Semantic-UI. All of which have plugins easily available to do the various add-ons you are looking for.
I really like Semantic UI: <a href="https://semantic-ui.com" rel="nofollow">https://semantic-ui.com</a>
They have a ton of elements and support themes for custom styles.
I've seen that foundation has something called blocks, that is more close to what I'm looking for but maybe too basic.<p>Would be cool some complete UIs built on top of popular frameworks.
