How do i change the mini logo of my website? at the top beside the name of your website, like for example for facebook it has a blue "F" logo and for bootstrap it has the 3 boxes blue pink and magenta. does it need something? Thank you!
If you mean the little icon that shows up on the browser tab, that would be called Favicon. You can have those created by going to any number of places, but this one I find is my favorite so far:
They give pretty good instructions on how to put them in the site, but for the most part just stick the links (all of them) they give you in your site's Head area (settings of your site where you would add HEAD content which will be for all pages then). Then just upload the images they gave you to your website. If you put them in a folder location you'll want to edit the paths of the code they give you for the HEAD to point each image to that location.
You need to be more clear on which image you're talking about so we can be sure we're covering the right one. I'm talking about the one on the browser tab, the little tiny one that you create called a Favicon.
Marrco is talking about the image that shows on your menu line as your logo itself.
"globe logo" is Chrome default for sites with no Favicon, so it looks like Jo' crystal ball was working better than mine.
Did you manually upload all the created icons to your website hosting provider as Jo said? Browsers ofter cache favicons, so you can try visiting your website with a different browser, or doing a hard reload.
BSS has a dedicated area for uploading favicons (which is what I believe this person is referring to.) Just go to File >> Design Settings >> Favicons (you will see it on the left in the vertical menu.) From there you can upload your favicon(s), which you will need to create outside of BSS. I use Photoshop to make mine.
