Technically yes, but in practice this is almost never the right answer. WordPress keeps one active theme across the whole site by design. You can work around it with conditional theme loading, but the maintenance cost of that arrangement grows with every update. The need behind the question, meaning a distinctly different look for selected sections, has three better answers today: style variations in a block theme, block patterns and page templates, and a multisite installation where the brands are genuinely separate.
Why WordPress runs one active theme
WordPress uses a single-theme architecture. One active theme controls the appearance of the entire site. That is a design decision, not a limitation waiting to be circumvented.
The relationship between themes and pages is simple: the active theme supplies the templates that determine how each content type displays. In a classic theme those are page.php, single.php, and index.php as the fallback. In a block theme, the equivalent files sit in templates/.
The constraint protects against specific problems. Two themes at once means two sets of scripts, two sets of stylesheets, potential function name collisions, and double the testing scope on every update. WordPress deliberately puts stability ahead of this particular flexibility.
Which means the question is worth rephrasing. It is rarely about two themes. It is usually about making a campaign landing page, a commerce section, or a second brand’s site look different from the rest.
How to get a different look without a second theme
There are three approaches, ordered from simplest to most involved.
Style variations in a block theme
Block themes support style variations: JSON files in the styles/ directory, each defining its own colour palette, typography, and spacing while using the same theme. A variation can be assigned to a specific template or to a section of the site.
This is WordPress’s native answer to the question of different appearances across different parts of a site. It needs no plugins, does not multiply code, and survives updates without intervention.
Page templates and block patterns
Custom page templates let you build layouts that depart from the rest of the site, a landing page with no header or footer, for instance. Block patterns give the marketing team ready-made sections to assemble on their own.
In most cases where the second-theme question comes up, a page template combined with a style variation is enough. The visual result is the same and the site stays one coherent system.
Multisite
If the sections are genuinely separate, meaning they have their own navigation, their own editorial team, and their own brand identity, then they are not sections. They are separate sites.
WordPress Multisite handles exactly that scenario: multiple sites in one installation, each with its own active theme, sharing a user base and plugin management. Updates happen once rather than separately for each brand.
For portfolios running to dozens of sites, the model goes one step further: a single shared codebase, a single design system, and central deployments, while each brand keeps its own visual identity. That’s the architecture covered in can multiple WordPress sites use the same database? That is an architectural solution rather than a configuration one, and it is normally a project in its own right.
When conditional theme switching makes sense
You can write code that swaps the theme depending on the URL, user role, or another condition. WordPress filters allow it. Plugins that do the same exist.
Before reaching for it, know what it costs:
- Testing scope doubles. Every WordPress, plugin, or theme update needs verification in both variants.
- Plugin conflicts become hard to diagnose. A plugin may work on one theme and fail on the other, and the ticket then reads “the site is broken, but only sometimes”.
- Performance drops. Two sets of assets mean higher memory use and slower rendering. Against Core Web Vitals that is a real difference, not a theoretical one. See how much weight Core Web Vitals carry for SEO in 2026 before accepting that trade-off.
- Maintenance needs someone who understands it. A solution written for one project is undocumented and ties the site to a specific supplier.
- SEO consistency becomes separate work. Meta tags, structured data, and heading hierarchy have to behave identically across both themes, and rarely do.
The scenario where this is justified is narrow: a temporary state, such as a gradual migration to a new theme section by section, with an end date. As a permanent arrangement it is usually not worth its price.
What to avoid
Theme-switching plugins in production. They tend to be poorly maintained and create a dependency that is not simple to remove later.
A parent theme acting as a framework that conditionally loads different stylesheets and template components. It sounds elegant. Two years in it is a collection of exceptions nobody wants to touch. A textbook case of a solution that costs most at exactly the moment you need to change it.
Different navigation and different interaction patterns between sections. Visitors do not perceive site sections the way the team that built them does. If menus, forms, and buttons behave differently after moving from one section to another, what drops is conversion, not just visual consistency.
How to make the decision
Answer three questions.
Do the sections share navigation and an editorial team? If so, it is one site. Style variations and page templates cover the difference in appearance.
Do the sections have separate brands, separate teams, and separate business goals? If so, they are separate sites. Multisite, or a shared architecture across a portfolio.
Is the difference visual or functional? If a section needs different functionality rather than a different look, the problem sits in the functionality layer, not the theme, and is solved with content types and plugins.
The second-theme question almost always turns out to be a question about site architecture. It is worth asking at the planning stage rather than a year later, once the first workaround is already deployed and being maintained.
FAQ: different themes
Does WordPress support two active themes at once?
No. Only one theme can be active. Conditional switching is possible through code or a plugin, but it doubles testing and maintenance scope.
How do I make a landing page look different from the rest of the site?
With a custom page template, optionally combined with a style variation. A second theme is not needed for this.
When is multisite the right choice?
When sections have separate brands, their own editorial teams, and their own navigation. At that point they are not sections of one site, they are separate sites.
Are theme-switching plugins safe?
We do not recommend them in production. They create a dependency that is hard to remove and complicate diagnosis on every update.
