Use the online code validation service below.

CODE TUTORIALS:

- https://www.w3schools.com/html/
- https://www.w3schools.com/css/

On line 18, in your sentence starting with :

<radest detta....

Directly in the code, not in the display view, replace the < with &lt ;... to get :

&lt;radest detta....

because the < character itself causes a problem and breaks the HTML structure.

That should correct your trouble.
