You can add the line of code to your theme file in the following ways:
Go to your Shopify Admin.
Navigate to Online Store > Themes.
Find the theme you’re using and click Actions > Edit code.
In the left sidebar, find and click on an existing CSS file in the assets folder (e.g., theme.css, styles.css, main.css). It depends upon your theme.
If you find an issue finding the css file, you can put the css in theme.liquid.
In the Shopify Admin, go to Online Store > Themes.
Click Actions > Edit code for your theme.
In the left sidebar, under the layout directory, click theme.liquid.
Inside the head tag, you can put the CSS
#shopify-section-template--21026794668356__featured_collection_bmtxpT .card-information,
#shopify-section-template--21026794668356__featured_collection_LaQQTG .card-information,
#shopify-section-template--21026794668356__featured_collection_WwxmRX .card-information,
#shopify-section-template--21026794668356__featured_collection_qq4kKE .card-information,
#shopify-section-template--21026794668356__featured_collection_a8mkey .card-information{
display:none !important;
}
This will work for you.
