## Change the Theme

The same way you could set the syntax highlighting theme with the key `"syntaxHighlight.theme"` (notice that it has a dot in the middle):

```Python hl_lines="3"
{!../../../docs_src/configure_swagger_ui/tutorial002.py!}
```

That configuration would change the syntax highlighting color theme:

transform: rotate(135deg);
L144:  -webkit-transform: rotate(135deg);
L145:}
L146:
L147:.daterangepicker .calendar-table th, .daterangepicker .calendar-table td {
L148:  white-space: nowrap;
L149:  text-align: center;
L150:  vertical-align: middle;
L151:  min-width: 32px;
L152:  width: 32px;
L153:  height: 24px;
L154:  line-height: 24px;
