Hello,
1/ Go to Header Builder, and change the width of the logo element in the header content area. Here you can find some videos about Header Builder – https://www.youtube.com/c/8theme/videos
2/ Go to Elementor > Post types, enable the editor for static blocks, then create a new static block with the desired content. Go to Header builder > add HTML element into the Top header area, and select your static block there.
