I found the Etsy Blog Team 's post "How to post images side by side" and used a HTML code they give.
I tried using the code but it didn't work so I didn't publish the post.
For my surprise all the posts with images side by side changed. The original edition I did was modified.
I don't know why the space between the images was increased and all the posts I edited in the whole blog with images side by side were altered and look awful
I don't have any idea how to change it back. I guess something was altered at the template.
It took me a lot of time trying the code... and this is the result. The strange is that I didn't even publish the post. Just trying it altered everything.
Be careful when using tips about HTML even if the site sounds reliable.
Thank you Etsy team...
I've redone this post according to the new size so that it could have the original format. The pictures have to be huge.
The rest of the blog... I'll relax.
