Best way to create add borders on webpage html? - html

Question

I want to make borders to be consistent throughout the pages. What do you think is the best method to do this? I have added an image below, I had in mind to have the red areas blank, cutting the menu borders and all the rest on the sides so it all looks aligned and centered. thanks a mil

Answer 1

The best way to do this would be to wrap your content within a container, and set the max-width for this (70%) or so, then if you want to add borders to this container you can do so.
Add <div class="container"> before any content you want to be centered/contained, then close the div at the end, and add the following to your css:
.container {
max-width: 70%;
margin-left: auto;
margin-right: auto;
}

Answer 2

Wrap your page inside a
<div id="wrapper">
your content here
</div>
/* add this to css */
#wrapper {
width:960px; /*put here the width you want*/
margin: 0 auto;
}
/*-----*/
