What are the advantages and disadvantages of using a ramp versus stairs for accessibility in a building?

Advantages of using a ramp for accessibility include easier access for individuals with mobility challenges, such as those using wheelchairs or walkers. Ramps are also safer and more convenient for people with strollers or heavy bags. However, ramps require more space and may be more expensive to install compared to stairs. Additionally, ramps may not be suitable for buildings with limited space or steep inclines.
