1. I see the widemode can be setting in config, but how to modify the template, add text in header(class=“css-1dp5vir e8zbici1”).
2. If I want to modify the margin-top, how to do ?

<div class="block-container css-k1ih3n egzxvld4" style="position: relative;">

.css-k1ih3n {
    width: 100%;
    padding: 4rem 1rem 4rem;
    min-width: auto;
    max-width: initial;
}
