Because I am a huge technomancing nerd and value creation of sacred space:
Comments in Code: Hide warding words, charms, or runes in code comments in the code of your site (< ! – – your ward here – – > sans spaces)
Invisible Sigils: Place sigils as images on a <div> layer set to an opacity of 0
Overarching Wards: Put any wards or enchantments in the CSS stylesheet to ensure coverage over your whole site, or to use your site as a “table” or well for an altar or general spell
