These proceedings present highlights of fiducial and differential cross-section measurements for several Higgs boson production modes and decay channels, offering a unique frame to study its properties at the Large Hadron Collider. The results are compared to Standard Model predictions and in some cases, limits on physics beyond the Standard Model are also extracted in the context of effective field theory models. The measurements use data collected by the ATLAS detector during pp collisions at a centre-of-mass energy of 13 or 13.6 TeV.
