Hello Ms. Morbenia Morbeck,
1. To remove the three mini black lines, please copy and paste the following CSS code into XStore >> Theme Options >> Theme Custom CSS >> Global CSS. After doing so, please clear your browser cache and check back to your site.
.et_b_header-menu .secondary-menu-wrapper .secondary-menu-toggle {
display: none !important;
}
2. To remove the yellow line below the sub-menu item on hover, please copy and paste the following CSS code to XStore >> Theme Options >> Theme Custom CSS >> Global CSS and then clear your browser cache.
.et-menu-list .subitem-title-holder a:hover:before {
display: none !important;
}
3. In order to reduce the space between the Sub Menu items, you will need to go to the Static Blocks and edit the particular static block which has been used for it. Then, edit the menu list item, and under the style tab, set the paddings as per your requirements. Please refer to the screenshot provided: https://postimg.cc/xNCvxHQH
We hope this information is helpful.
Best regards,
