Make icon greyscale

I can convert it to scalable SVG! you can then use my modifications here to make the icon work better.

Do you have bigger size of the icon? I need much bigger than 48×48. 512 x 512 would be suitable.

Any time, just send me the big version of that icon (512×512 or bigger).

Hello,

Has been a hard year for me as my father passed away so sorry for this taking so long.

I finally got it the official WordPress way. As it comes from svg inline rather than it supports hover and selected coloring:

Changes
Here are the changes it works with, only added svg as inline and things in variables inside add_menu_page() function to easier management, I hope you will accept it: https://github.com/ronilaukkarinen/wp-fastest-cache/commit/81b96df5ec94d0a8197ce412c2ded2e78c525620

All the best,

Thanks! Couple of issues:

1. the icon is not direct inline svg format (that WordPress supports by its function) but inside which makes the image a bit unsharp. Also the size is a bit over the area that is usually reserved for the icon, don’t you think? Did you look my code suggestion in my earlier message https://github.com/ronilaukkarinen/wp-fastest-cache/commit/81b96df5ec94d0a8197ce412c2ded2e78c525620#diff-9898b34307db8359d47bf3dd05eccbf4 ?

2. I still see colored version in the upper menu https://i.imgur.com/NqXCnfk.png

Can these be tweaked? 🙂

OK, good! You can add @rolle or Roni Laukkarinen. 🙂

Hello.

I noticed a bug on smaller devices, there’s forced margin-left: 0 that causes the misalignment: https://i.imgur.com/Ekp3ucg.png

Can you remove that line (line 122, #toplevel_page_wpfastestcacheoptions div.wp-menu-name) so it will work, thanks!
