We recommend to only activate the theme editor when you possess sufficient knowledge of HTML and CSS.
Editing a theme
When you activate the theme editor, you will no longer receive theme updates. If for example, when Lightspeed or another theme developer provides an update for a given theme, the update code is added to the main theme code, as it resides on our servers. Connected to that main theme are all online stores that have it installed. Whenever the main theme is updated, the update will also be implemented across all connected stores.
However, if you activate the theme editor, your online store will be disconnected from the given main theme and regarded as having an edited version of the theme. If updates occur to the main version, it will not implemented in your store. You may contact the theme developer periodically to inquire about any updates you may be missing.
You can find more information in our Developer centre.
