# CSS Image Examples

```
.round  {
  border-radius: 50%;
}
```

Take some time and fiddle with these settings to understand HOW they work.

```
.thumbnail{
  border: 1px solid #ddd;
  border-radius: 4px;
  padding: 5px;
  width: 150px;
}
```

Now you will see a change when you put your mouse hovers overan image file&#x20;

```
img:hover {
  opacity: 0.2;
}
```

Now add two different images to your HTML folder. Use the same `<img>` tag as  before, but don't but in a height or a width - just the `src` and the `alt`

Now adjust  the settings for width and opacity, try and add a border or center it

If you are feeling crazy - use this to add a separate section at the top of your website

```
.header {
  background-color: #F1F1F1;
  text-align: center;
  padding: 20px;
}
```
