How remove underline in link in react

Question

How set text-decoration to none in react of the link child text? In my case this text with the 'preview-title' and 'preview-slogan' class. I tried set it in app.css

.preview-title, .preview-slogan { text-decoration: none; }

As well i did that to a tag in index.css

a { text-decoration: none; }

Also attempted textDecorationStyle to the element <div className='preview-title' textDecorationStyle="none"> But that doesnt work too

In devtool we see the style is applied through .css but at the page it still with underline

Found out, it must be placed text-decoration: none in app.css, not in index.css.
