Theme basics
Themes are an easy way to adapt an existing design or to create a new one for an Aimeos online shop. A theme only consists of CSS and Javascript to style and animate the structural HTML. In combination with the possibility to rearrange the sub-parts of the front-end, it's a powerful way to completely redesign a shop without touching the HTML code.
The default themes are located in the client/html/themes directory of the aimeos/ai-client-html extension. Each theme has its own directory containing the CSS and Javascript files as well as its images. The shared Javascript files are located in the base directory, which are used by all themes.
Structure#
A theme must consist of these files and directories:
- email.css
- Contains the CSS styles that are used by the HTML e-mails.
- aimeos.css
- All CSS styles which makes the theme unique. You may also include styles that are necessary for any jQuery plug-in that is used.
- aimeos.js
- Additional Javascript code for animations or to modify the existing JS code.
- media/ (optional)
- Directory for all images, fonts and other media items that are used by the theme. They must be referenced relative to the aimeos.css file like "url(images/aimeos.png)".
Cascading Style Sheets#
CSS is a very powerful style sheet language to describe the presentation for the existing HTML structure. It is possible to create a totally different layout by using individual styles for the same HTML elements.
Tip
If you want to create a new theme it is best to start with a CSS file of an existing theme. Their CSS definitions already contain a great amount of brain-power which makes them compatible with different browsers and for different devices like smartphones or tablets.
CSS classes and selectors#
Styling the HTML for a theme is pretty straight forward as each component and almost all of its child elements have CSS class attributes associated to them. The root node of each component also contains a CSS class named "aimeos". Thus, you are able to identify and style all components that belong to the web shop at once, e.g. applying a font definition to the "aimeos" CSS class.
<section class="aimeos account-history">...</section>
<section class="aimeos catalog-filter">...</section>
<section class="aimeos catalog-detail">...</section>
<section class="aimeos basket-standard">...</section>
<section class="aimeos checkout-standard">...</section>
Furthermore, each component can be uniquely identified by its CSS class. The catalog detail component has the class "catalog-detail" for example. The names of the CSS classes for all other components follow the same naming scheme which is
<component type (catalog)>-<component name (detail)>
Since some components are built from several subparts (e.g. the "catalog-detail" view consists of the main template and a service section), each subpart has its own CSS class (e.g. "catalog-detail-service"). Additionally, subparts of subparts have their own CSS class too if they exist. This allows you as a theme designer to uniquely identify each subpart and apply a specific styling.
Tip
When defining new styles for a theme, always start with the CSS class of the subpart you want to style and then the class that is associated to the relevant HTML node, e.g.
.catalog-detail-basic .name {
font-size: 125%
}
For partials used several times at different locations, the same CSS classes apply to all locations. Examples for those classes are:
- product
- media-list and media-item
- price-list and price-item
Warning
Don't use simple CSS classes like "product", "name" or similar for styling without a class identifying the component or the "aimeos" CSS class. This will cause side effects to the HTML the components are embedded into!
Responsive web design#
Today, we have very different device sizes starting from small smartphones with 320px width to huge TVs that span 3960px in width and countless device widths in between. The art of web design is to create pages that look great on all of these devices.
Tip
Frameworks like [https://getbootstrap.com/ Twitter bootstrap] provide fluid grid systems that help developers create web sites optimized for different device sizes.
The first rule of responsive web design is: Avoid fixed measure units like px! They are only useful for defining a maximum or minimum device width for media queries. If you pay no attention to this advice, your theme will scale miserably! If you define a margin of 50px to both sides of a div container it will eat up most of the space on a smartphone and won't be noticed on a 4k TV. Instead, use
- "%" for relative widths and font sizes
- "rem" for fixed widths
- "rem" for heights
Dump all thoughts about pixel perfect layouts immediately to the trash bin! Layouts must be fluid and adapt to the content, not the other way round.
Javacript#
The Javascript code of a theme should only be used to improve site usability (by doing client side checks), to display necessary content, and to create animations. It should NOT be essential to use the shop! This usually results in poor usability for your site's visitors who do not use a mouse.
It's guaranteed that these jQuery libraries are available and included before the aimeos.js file:
- jQuery
- jQuery-UI (customized, detail page only)
The jQuery-UI package contains the following features:
- core
- widget
- mouse
- position
- autocomplete
- menu
Tip
If you need additional jQuery-UI plug-ins for your theme, you can add them to the aimeos.js file of your theme. As they can be very big, you should be careful what you want to use in your theme. Otherwise, customers will be disappointed with the page load time.
The Aimeos shared library files contains some objects that are named just like the HTML clients that are available as components:
- Aimeos
- AimeosAccountHistory
- AimeosAccountFavorite
- AimeosAccountProfile
- AimeosAccountSubscription
- AimeosAccountWatch
- AimeosBasketBulk
- AimeosBasketMini

- AimeosCatalog
- AimeosCatalogDetail
- AimeosCatalogList
- AimeosCatalogFilter
- AimeosCatalogStage
- AimeosCatalogSession
- AimeosCheckoutConfirm
- AimeosCheckoutStandard
- AimeosLocaleSelect
These Javascript objects are globally available and their methods are responsible for executing the implemented actions if the required HTML DOM nodes are available. You can extend or overwrite each method to perform additional action, another action, or no action at all. The article about adapting existing themes has more information and examples of how to do this in detail.
Note
To initialize the objects and set up the available methods, the init() method of each object is called after the DOM is ready.

/**
* <type> <component> client actions
*/
Aimeos<type><component> = {
/**
* Initializes the <type> <component> actions
*/
init: function() {
}
}
Please replace the placeholders for
AimeosCatalogMysubpart = {}
