what code do I use to justify a text within a single page?

Site URL: https://www.jasmine-noronha.com/about

hello! i managed to use the following code to justify the text on my website: 

body p, .sqs-layout .sqs-block.html-block p {
 text-align: justify !important;
}

it worked. however, it justified all the text in my site. and i'm just looking to justify the text in the "about" page. please help! 

Edit above page > Add Code Block > Paste this code

<style>
  body p, .sqs-layout .sqs-block.html-block p {
 text-align: justify !important;
}
</style>

@tuanphan that worked - thank you!
