I think that you can find many examples of stylistic devices in Bradbury's short story. The fact that the short story is the chosen form is powerful. In selecting the form of a short story, Bradbury is able to forcefully drive home the emotional dynamics of Margot and her classmates in a brief and powerful setting. At the same time, the short story delivers the idea that Margot's story is a small one, but one that resonates quite lucidly. The symbolism of the closet is another example of stylistic device that Bradbury brings out to heighten a theme of tyranny of the majority. The fact that Margot, the only person who speaks the truth of the sun and the minority, is thrown into a closet and forgotten in one helps to enhance the work's assertion that silencing voices is antithetical to any pursuit of democratic notions of the good. I would also suggest that Bradbury's use of imagery is quite intense. The creation of the sun and all that it brings as the personification of pure joy is powerful. Margot is the only one who understands it and she is rejected by her peers. When they enjoy the sun and all that it brings, they do so alone, while she is locked in the closet. Only when the sun leaves, when happiness is gone, do the children recognize that Margot is still locked up in the closet. The image of the sun and the more potent image of Margot being unable to experience it while the others do is lingering inside the mind of the reader long after the story is completed.
