« Optimiser la perf' par un choix optimal des dimensions des images RWD », Nicolas Hoizey — WLS 2018

From a channel Lumen includes in full: This is a non-profit web performance conference that publishes recorded expert talks. Every sampled transcript is an expert teaching technical or practitioner material, such as browser loading internals, HTTP/3, DevTools debugging, CSS rendering, responsive images, performance budgets and INP optimization. The few non-talk uploads (the interactive quiz, and any teasers, openings or promos) can be caught by title patterns.
