Refine the site on WP (WordPress)

There are a few projects that need improvements, mostly small ones, most of the projects on WP. Major edits:
add new blocks
fix page spacing
Old blocks are jammed in places, adjust their work (they climb where it is not necessary, fonts jump, run over each other)
integrate and configure the lastmod
try not to break other blocks
fix resize pictures
The price is negotiable. Tk I will prepare.
