I need an Excel Expert VBA code Hide Rows based on Cell value

I need help adding multiple same type of macros to the same Sheet. I am using one to hide rows 5 to 11 if cell b3 has "No", "N/A" or is blank and doesn´t hide them if it has "Yes". Now I want to add the same type of macro but for another range and based on another cell value, but I don´t know how to add more than two macros to the same sheet. For example if B13 has "No", "N/A" or is blank it will hide cells 15 to 19 and if it has "Yes" it will not hide them. if B25 has "No" "N/A" or is blank it will hide rows 23 to 29 and if it has "Yes" it will not hide them. I need to know how to add as many as I need since the original file has many cells that need to be hidden based on many cell values.
