Component Object Positioning
Webflow doesn't have much support yet for styling of component instances. Here's a technique we use to support the adjustment of images that may be off-center.
Use Cases
The general use case scenario for this is that you have;
A CMS collection that contains a primary photo, such as a product image, a blog hero image, or a team member's profile photo.
In your collection pages and collection lists, you want to constrain the aspect ratio of that photo, so that it's 1:1
Due to the variety of the photos, that cropping may not always be centered, so you need a way to adjust this per collection item.
We can solve this using Webflow components, property-bound custom attributes, a small piece of CSS, and Webflow's property-to-CMS binding capabilities.
In the end result, we can adjust the camera position on each image individually by e.g. specifying left up to move the camera position left and upwards slightly.
Usage Notes
Once setup you control the positioning with a string value that can contain a horizontal camera position and/or a vertical camera position.
All positions here are "camera positions". meaning that "left" moves the camera left, and the image shifts to the right.
| Horizontal Position | Vertical Position | |
|---|---|---|
0% | start | top |
25% | left | up |
50% ( default ) | center | middle |
75% | right | down |
100% | end | bottom |
For example, start up would move the camera all the way to the left, and slightly upwards in the image.
Ratios and Object Fit
In most cases, this feature will be setup on an image which has been set to a ratio of e.g. 1:1 , ond object-fit: cover.
What this means is that the image will fill the space, and one of the dimensions ( width or height ) will already be at 100%.
As a result it generally only makes sense to specify either the horizontal camera adjustment or the vertical camera adjustment, but not both.
In the 1:1 example;
A perfectly square image already fills the space perfectly and cannot be adjusted at all as there is no more image to see.
A portrait image would already be showing its full width and the camera can only be adjusted vertically.
A landscape image would already be showing its full height, and the camera can only be adjusted horizontally.
Getting Started
This will be integrated into the SA5 lib later, for now it's a manual setup.
On the component wrapper, put a custom attribute of wfu-component-position.
Bind its value to a component property, called Camera Position. This is where you'll enter e.g. top left when you want to adjust an item's position.
Inside of the component, add a custom attribute of wfu-component-position-item to the elements to which you want the CSS applied. Generally that will be your main image element.
Make certain the image elements are setup properly, e.g.;
e.g. width 100%, height 100% if they need to fill the container
Overflow clip
Fit cover
Default fit cover position is usually centered at 50% 50%
Add an embed inside of your component, with this CSS;
Best Practices
If you're using the CMS, and have added a text field to control these positions, We recommend you name it e.g. Profile Photo Camera Position,
You can can also add this note to help the admin remember the keywords needed.
