My goal is to centralize all the elements on a webpage so that when the browser size is modified, the content shifts accordingly. Currently, I am using the following CSS code:
margin: 0px auto;
width: 670px;
However, I am facing a challenge in trying to have a colored header that spans 100% of the width, while also ensuring that the text within the header adjusts along with the rest of the page. How can I achieve both of these requirements simultaneously?
