# --description--

|

You are getting closer. The next thing to do is to set the `viewBox` attribute of the `svg` element. This will
|
||||
control how much of the image is visible. The first two numbers set the center of the image.
|
||||
You are getting closer, now look at this example:
|
||||
|
||||
The following two numbers set the size of the image we can see: width followed by height.
|
||||
```html
|
||||
<svg viewBox="0 0 50 50">
|
||||
</svg>
|
||||
```
|
||||
|
||||
Since here the entirety of the icon should be visible, you should set the `viewBox` attribute to `0 0 24 24`.
|
||||
The `viewBox` attribute controls what part of the image is visible inside the SVG.
|
||||
|
||||
- The first two numbers (`0 0`) set the starting position of the `viewBox` — the top-left corner (x and y).
|
||||
- The next two numbers (`50 50`) define the `viewBox`'s width and height.
|
||||
|
||||
Set the `viewBox` attribute to `0 0 24 24`.
