Please, how do i use css to hide all joomla image post in certain mobile devices size to reduce loading time? Also, how do i make text 'h1, p' in my carousel responsive? It seems to be too big and occupied large space on mobile phone wit small screen size. View the css below;

Don't use px as font-size unit. Use em or rem which inherit.

Give the element a class "hidden-phone"
