Display Blog Post Titles Only

With the help of CSS you can achieve this.

So here is the code which will help you hide the content and to let you show only the titles.

.entry-content {
display: none;
}

Your can add this code through the theme’s functions.php (It is better to create a child theme so that your custom code will not get deleted when the theme updates.) or you can write this in your custom plugin.

Note: Write the code which conditional add this css only to the page which you have specified to avoid it interfering on other pages.
