Architecture for customizing user interfaces

A computer-implemented method comprising:

• modifying guest instructions using a first user interface style to generate first customized guest instructions that are customized for use by a first client device, wherein the first customized guest instructions include a first customized variant of a user interface element to which the first user interface style is applied, wherein the first customized guest instructions configure the first customized variant of the user interface element to initiate a function in response to interaction with the first customized variant of the user interface element;
• modifying the guest instructions using a second user interface style to generate second customized guest instructions that are customized for use by a second client device, wherein the second customized guest instructions include a second customized variant of the user interface element to which the second user interface style is applied, wherein the second customized guest instructions configure the second customized variant of the user interface element to initiate the function in response to interaction with the second customized variant of the user interface element;
• providing the first customized guest instructions to the first client device;
• and
• providing the second customized guest instructions to the second client device.

An apparatus comprising:

• at least one memory;
• and
• at least one processor coupled to the at least one memory, the at least one processor configured to:
• modify guest instructions using a first user interface style to generate first customized guest instructions that are customized for use by a first client device, wherein the first customized guest instructions include a first customized variant of a user interface element to which the first user interface style is applied, wherein the first customized guest instructions configure the first customized variant of the user interface element to initiate a function in response to interaction with the first customized variant of the user interface element;
• modify the guest instructions using a second user interface style to generate second customized guest instructions that are customized for use by a second client device, wherein the second customized guest instructions include a second customized variant of the user interface element to which the second user interface style is applied, wherein the second customized guest instructions configure the second customized variant of the user interface element to initiate the function in response to interaction with the second customized variant of the user interface element;
• provide the first customized guest instructions to the first client device;
• and
• provide the second customized guest instructions to the second client device.
