Default them of Osclass 8 is sigma.

In this theme have bee used Fontawesome 5.14. therefor we only use free version of 5.14 or other 5 version therefor we can not use 7 version.

But what we can insert in (icon input box)

Only full class name of free icons of version of 5 of fontawsome

https://fontawesome.com/v5/icons#packs

for example:

https://fontawesome.com/v5/icons?t=categories

https://fontawesome.com/v5/icons/socks?f=classic&s=solid

<i class="fas fa-socks"></i>

only insert in (icon input box) the following text in () without ():
(fas fa-socks)

Does anyone want to guide?

Means:
#001122

Thanks for response.

You learned me to change color of icons by putting #001122 in (color input box).

I want to know what must put in (icon input box) for changing shape of icon?

If we must type name of fontawesome  icon name please say my or show a link to show how to use font awesome in sigma theme?

Please help me and help other people who do not know what must add icons.

Sigma itself does not use icons, it's here for further development and future compatibility.
Themes usually use own system to load icons & colors now.
If you want to use it on Sigma, you must implement it.
Form of icon is free - depends on your usage. Can be font awesome clsss, font awesome HTML element but also image link or blob.

... also image link ....

If i have an ability for insert images in a directory and insert link in the (icon input box), Please help me by show an example.

for axample say me put image in site.com/specefic-image-folder

then insert this

site.com/site.com/specefic-image-folder/icon-01.gif

Example: https://mysite.com/img123.jpgUsage: <img src="<?php echo $cat['s_icon']; ?>"/>

Example:

Code: [Select]

https://mysite.com/img123.jpgUsage:

Code: [Select]

<img src="<?php echo $cat['s_icon']; ?>"/>

This is not useful.
But i found solution.

Yes using font awesome 5 is correct.
