This post should display a **header with an overlay image**, if the theme supports it.
|
|
|
|
Non-square images can provide some unique styling issues.
|
|
|
|
This post tests overlay header images.
|
|
|
|
## Overlay filter
|
|
|
|
You can use it by specifying the opacity (between 0 and 1) of a black overlay like so:
|
|
|
|
![transparent black overlay]({{ "/assets/images/mm-header-overlay-black-filter.jpg" | relative_url }})
|
|
|
|
```yaml
|
|
excerpt: "This post should [...]"
|
|
header:
|
|
overlay_image: /assets/images/unsplash-image-1.jpg
|
|
overlay_filter: 0.5 # same as adding an opacity of 0.5 to a black background
|

|
|
actions:
|
|
- label: "More Info"
|
|
url: "https://unsplash.com"
|
|
```
|
|
|
|
Or if you want to do more fancy things, go full rgba:
|
|
|
|
![transparent red overlay]({{ "/assets/images/mm-header-overlay-red-filter.jpg" | relative_url }})
|
|
|
|
```yaml
|
|
excerpt: "This post should [...]"
|
|
header:
|
|
overlay_image: /assets/images/unsplash-image-1.jpg
|
|
overlay_filter: rgba(255, 0, 0, 0.5)
