Hey Fabio,
Out of the box, it is not possible to make the featured image span the full width of the page because it is part of the content area which is contained by the Site Layout settings.
It’s not recommended to customize this if you’re not a web developer because custom coding has the potential of breaking your site or custom codes might not work in the future. But, if you wish to proceed, you can try adding this code in Theme Options > CSS to make the Ethos featured image span the full width of the page while retaining the width
and max-width
of the content. Please note that you will adjust those in the CSS and the Theme Options won’t apply in this case.
.single-post .x-container.max.width.main {
width: 100% !important;
max-width: 100% !important;
}
.single-post .entry-wrap,
.single-post .x-comments-area {
width: 88%;
max-width: 1240px;
margin: 0 auto;
}
If you also want to literally center align the text of the headline, please add this code still in the CSS area.
.single-post .entry-title {
text-align: center;
}
Hope that helps.
