When to use slider ux?
Sliders are excellent UI controls, but they are not one-fits-all tool. They are good when users want something that is relative, but not very good for exact values. When designing a slider, measure interaction cost and make sure that the users can select that range (or single value) correctly from the first attempt.
Are sliders bad for accessibility?
Since sliders feature rapidly moving images, they can pose some issues in terms of accessibility, especially for those with visual impairments. Moreover, these sliders are often controlled by a series of small buttons or arrows that aren't as contrasting with the background, making it difficult for them to see.
