Hello sanjaytlm,
=> Put below css code into Additional CSS textarea (Dashboard >> Apperance >> Customize) then click on Save & Publish button.
=> If there is no Additional CSS option then put below css code into your current theme’s style.css file located at wp-content/themes/your_current_active_theme/ folder.
#hs-site-branding img{
width: 260px;
max-height: 100px;
}
.hs-container #hs-site-branding{
margin-top: -10px;
}
header.fadeInDown .hs-container #hs-site-branding{
margin-top: -20px;
}
Note : All Changes you done in style.css or other file are gone when you update theme. So prefer Child Theme
Hope this will helps you.
