After activating the theme, you will notice that a new submenu item appeared, under "Appearance -> Customize".
If you click on it you will be taken to the WordPress customizer, a tool which will allow you to modify the look and feel of your website.
Unfortunately not all theme options features are present. You can select only the body background color, background image, custom header image, logo & favicon.
Login to WordPress admin panel (URL should be www.yourdomain.com/wp-admin )
Navigate to "Settings > Reading".

From dropdown, select which page you want to set as "Front Page" and which page you want as “blog posts” page. Default Front Page is ‘Home’ and default posts page is ‘Blog’.

Click on ‘Save Changes’ button to save all.
Step 1: Navigate the Add New menu under the Pages Navigation.
Step 2: Select your header style and Give it a title.
Step 3: Use Elementor for your page Customization.
Now you can customize the page with elementor page builder.
