# Components
Vide encourages separating different parts of your UI into functions called
*components*.
A component is a function that creates and returns a piece of UI.
This is a way to separate your UI into small chunks that you can reuse and put
together.
::: code-group
```luau [Button.luau]
local create = vide.create
local function Button(props: {
Position: UDim2,
Text: string,
Activated: () -> ()
})
return create "TextButton" {
BackgroundColor3 = Color3.fromRGB(50, 50, 50),
TextColor3 = Color3.fromRGB(255, 255, 255),
Size = UDim2.fromOffset(200, 150),
Position = props.Position,
Text = props.Text,
Activated = props.Activated,
create "UICorner" {}
}
end
return Button
```
```luau [Menu.luau]
local create = vide.create
local Button = require(Button)
local function Menu()
return create "ScreenGui" {
Button {
Position = UDim2.fromOffset(200, 200),
Text = "back",
Activated = function()
print "go to previous page"
end
},
Button {
Position = UDim2.fromOffset(400, 200),
Text = "next",
Activated = function()
print "go to next page"
end
}
}
end
```
:::
A single parameter `props` is used to pass properties to the component.
