CSS code not working on single page code injection

Site URL: https://mushroom-sapphire-grdc.squarespace.com/

That bloc id is for a specific image, Custom css applies it to all pages, so the one with the block will work, but if you post it in the header of any single page, it will not. This means you need to target the image block id put it in the code and apply the code to the page the image is on. You can id specific blocks with a free Chrome plug in:  https://chrome.google.com/webstore/detail/squarespace-id-finder Once you id the block just change it in your code insert in the header of the page you want. 

Thanks Derrick,

That is the plug-in I used to id the block.  Like I said previously, it works when added to Design>Custom CSS, but I am not sure how to write it if I just wanted to add it to the Page Header Code Injection area of my blog page instead of the Design>Custom CSS area.

Oh, now I see, to add it to just one page, just add this to the front and end of the code 

<style>

actually when you type that into the header it will add the second <style> command just paste the code between then two. 

I did that and it did not work.

I put this into the Into the Blog Page>Advanced>Page Header Code Injection:

<style>#block-yui_3_17_2_1_1596655451516_4134 {.image-overlay {box-shadow: 0px 0px 10px 4px (#fff);}}</style>

I have code for specfic blocks on certain pages in custom css, sometimes that is the only way to get certain effects to work. 

I appreciate you reaching out.  I originally put everything in the Design>Custom CSS area.  I was hoping to tidy up the site by moving CSS that only effected single pages pages over to the Code Injection areas.  No worries, it still works in the Custom CSS area.  Thank you!

My code injection doesn't work on mobile devices on Product pages my client website. Stop working yesterday. I didn't have the problem before. Thank you for your help.
Please check this page. I can't rate the product and write review on iPhone, any mobile device. I test it both browsers Google and Safari on mobile and it doesn't work. 

I am using Facebook Comment Plugin code and Rating-Widget code in code injection and code blocks.

Hi. Have you solved this yet?

@tuanphan Hi, I'm having the same issue. I've entered CSS to change the background color of store and product page, however, on mobile and incognito, the background does not show up on page load (once I reload, it appears; have had it tested on other phones and same problem.)

And the custom code used on this specific page's Page Header Code Injection is below:

<style>
.Main {
background-color: #212931 !important;
}
</style>

I've also tried applying the CSS to the site, targeting the specific store pages—this solves the loading problem for the store pages, but is NOT applying the background color to all product pages within that store. That code used is here:

body#collection-6094f797c91c8270768fdbf7 .Main {
    background: #ffffff !important;

As you're using a Brine family template, you should only add your styles to Design > Custom CSS. Your site's template uses Ajax Page Loading to improve performance (read more) and so you should not add styles using Code Injection. They'll only load whilst you're logged on; visitors won't see them (except on refresh).

Regarding store pages, they'll have a collection class (prefix with ".") not a collection ID (prefix with "#"), so your CSS would start with:

body.collection-6094e977b128ae3b58601c3b
