This option allows you to add your own logo to the website. The exact logo size may change depending upon the header layouts. If you remove the logo, then the Website title will display instead.
If you wish to show the website title instead of the logo, then you can remove the logo and the site title will show up.
This option will allow you to change and edit the text of the Site title in the header.
This option allows you adjust the position of the logo image. The values in this option are in the clockwise direction. So for example, if the values are: 0px 0px 0px 0px - then the sequence of these options would be (Top Right Bottom Left).
You can setup the Site icon by uploading the image from here. The Site Icon is used as a browser and app icon for your site. Icons must be square, and at least512 pixels wide and tall.
