Privacy

Go PRO Window blinds lowered to protect code. Code Editor with window blinds (raised) and a light blub turned on.

Keep it secret; keep it safe.

Private Pens are hidden everywhere on CodePen, except to you. You can still share them and other people can see them, they just can't find them through searching or browsing.

Template

Make Template?

Templates are Pens that can be used to start other Pens quickly from the create menu. The new Pen will copy all the code and settings from the template and make a new Pen (that is not a fork). You can view all of your templates, or learn more in the documentation.

Template URL

Any Pen can act as a template (even if you don't flip the toggle above) with a special URL you can use yourself or share with others. Here's this Pen's template URL:

                <h1>at-grid</h1>
<p>A simple, display:table -based grid layout tool.</p>
<p>In most cases, you can use columns on their own: browsers understand that there is an implicit row and grid.  My understanding is that this is fairly universal, but I would appreciate feedback on this subject.  Please, open this up in as many different browsers as you can find, and check if they look <em>the same</em>.</p>
<p>Each component has a different background color: grids are green, rows are red, and columns are blue.  Non-grid container elements have a gray outline.</p>
<p>→ [at-grid-col]s with a display:block wrapper element and no explicit sizing:</p>
