finding non bootstrap components

Why is it not possible to find CSS components (or indeed any components/templates) that do not use Bootstrap. I do not like it and many many many items are rammed with bootstrap div’s to the point of madness. I am just looking for clean thought out code rather than . I waste a significant amount of time dismissing items with bootstrap and the search function will not allow for omitting items containing the word bootstrap… It’s just seriously frustrating trying to find well coded items.
