## Reviews
### [Blocks Media view](https://wordpress.org/support/topic/blocks-media-view/)
[Bub](https://profiles.wordpress.org/jdenning47/) Alunsun 28, 2026
This plugin block me from viewing my media files when I am, for instance, trying
to add an image block to a page. Except for this I think it is an excellent plugin.
My work-around will be to disable this plugin while adding any image media and re-
enabling it when I am done.
### [So simple yet works perfect!](https://wordpress.org/support/topic/so-simple-yet-works-perfect/)
[cengoguven](https://profiles.wordpress.org/cengoguven/) Alunsun 22, 2026
İt’s so easy to use and does the job as described.
### [Useful but doesn’t know modern properties](https://wordpress.org/support/topic/useful-but-doesnt-know-modern-properties/)
[ellissei](https://profiles.wordpress.org/eliseimiron/) woosun 8, 2025
Simple and useful, but modern CSS properties like clamp(), repeat(), margin-inline,
or less common units like dvh throw syntax errors. For beginners, this can be really
confusing.
### [Fantastic!! But abandoned??](https://wordpress.org/support/topic/fantastic-but-abandoned/)
[sintow](https://profiles.wordpress.org/sintow/) abɔxwisun 23, 2024
Have been relying on this plugin for several years. The problem is that it appears
to have been abandoned, leading to warnings on popular security sites and plugins.
It would be so great to have it updated again!
### [Works out of the box](https://wordpress.org/support/topic/works-out-of-the-box-150/)

No settings needed for this plug in. It just works. Great choice for customizing
footers and headers.

now it will appear in the HEAD as:
```
```
…even though no css file is actually generated.
