Hello Lukasz,
The main issue found in your site it that you have directly edits style.css
in ‘catch-box’ theme directory. You shouldn’t not add or edit any files inside ‘catch-box’ theme directory all your changes will be reverted back to original when you update or upgrade the theme. So, the best option to add css will be either from “Appearance => Theme Options => Custom CSS” box or by building child theme and adding it in your child theme style.css
Also your css changes has effect the responsive design of your site. We cannot see log in small screens. So, first restore the original style.css
file.
For padding you can add the following css:
#header-content {
padding-top: 25px;
padding-bottom: 25px;
}
For title position as per your style.
#site-title {
top: 34%;
}
