How can I center the title on my default contact page?

Hi @Tiagiinho

The changes you did working perfectly, but I have theme oriented change which you can follow if you want.

First go to header.liquid file and comment out the code as below at line number 674

if (this.predictiveSearch && this.predictiveSearch.isOpen) return;
/*
      if (scrollTop > this.currentScrollTop && scrollTop > this.headerBounds.bottom) {
        if (this.preventHide) return;
        requestAnimationFrame(this.hide.bind(this));
      } else if (scrollTop < this.currentScrollTop && scrollTop > this.headerBounds.bottom) {
        if (!this.preventReveal) {
          requestAnimationFrame(this.reveal.bind(this));
        } else {
          window.clearTimeout(this.isScrolling);

          this.isScrolling = setTimeout(() => {
            this.preventReveal = false;
          }, 66);

          requestAnimationFrame(this.hide.bind(this));
        }
      } else if (scrollTop <= this.headerBounds.top) {
        requestAnimationFrame(this.reset.bind(this));
      }
      */

Then, add below css in base.css at bottom

#shopify-section-header {
	z-index: 20;
	position: sticky;
	top: 0;
}

This quick solution will work using theme existing code change with minimum effort and with some theme animation.

Thanks
