How does stacking STX work?

Could you kindly elaborate on the mechanism of stacking STX? I'm curious to understand the process, including the technicalities involved and how it impacts the overall functionality and value of the STX tokens. Could you also explain the benefits that stacking STX offers to its holders? Is there a specific time frame or conditions that need to be met for stacking to be effective? Thank you for your assistance in clarifying this concept.
