IPFS works pretty well in the style of progressive-enhancement with the existing web for static content specifically. If you want to link to a resource that's available through IPFS, then you make the link point to an IPFS gateway that you trust and expect to stay online (possibly your own on your own domain), like https://example.com/ipfs/Qm_IPFS_HASH_HERE/. Anyone that has a browser with direct IPFS support (either because they're using an IPFS extension or they're using a browser with built-in support, which might get more popular if IPFS takes off) will have their browser recognize the URL format and just fetch the file by hash directly from IPFS, and it won't matter if example.com is still up and serving the file. For everyone else, the link will work as long as example.com is still up and acting as an IPFS gateway. If example.com ever goes down, then users can make the link work by installing an IPFS extension or manually replacing the example.com domain in the link with the domain of any still-active IPFS gateway, and any admin in control of the page could fix the link similarly.
