label 上加一个 justify-center 类名就可以
```
<label class="cursor-pointer grid place-items-center justify-center">
<input type="checkbox" value="synthwave" class="toggle theme-controller bg-base-content row-start-1 col-start-1 col-span-2"/>
<svg class="col-start-1 row-start-1 stroke-base-100 fill-base-100" xmlns="
