1: Create a new file in NameX/css/custom/custom_edits.css. Then add the following:
#messageindex #topic_container .board_stats p,
#messageindex #topic_container .board_stats p strong {
font-size: 11px;
}
2: You can change this through the default settings of the forum. Go to Admin > Forum > Attachments and Avatars > Avatar Settings. In there you'll notice four settings related to width and height. Adjust the values to something smaller.

3: I'm not sure what you are trying to accomplish. You could hide more things from the poster. For example, in the file you created for the first image, add the following:
#forumposts .poster ul.user_info li.blurb,
#forumposts .poster ul.user_info li.im_icons,
#forumposts .poster ul.user_info li.profile,
#forumposts .poster ul.user_info li.title {
display: none;
}

Ok - but I have no idea about CSS  other than giving a hint where to change it in existing CSS file or providing a code. Just 3 examples:
image #1 - numbers of post - reducing font size
image #2 - on desktop view area of user - avatar smaller - personally I would like to smaller completely
image #3 - can a post be done completely smaller?

if it too much / not possible - I think I nee dot lean more. link to forum is https://forum.depmod.com

Thanks

Yo can add your own CSS to overwrite styles.
Create a file in NameX/css/custom/custom_edits.css

You can also tweak responsive.css for some mobile changes, or include the media queries in the new file.

Hallo,

I have question about this great theme as a newbie:

possible to change font sizes in some areas? Or is there an MOD available which can do this so there is no need to go deep into CSS files?

I can share areas where we want to have it smaller basically - on mobile view and desktop view

Thanks

I need to buy this theme or another similar one with a good look, there are only 2 themes in the SMF Tricks store

De momento no estoy disponible.
Quizás en el futuro.

Saludos

Not available at this time, it's up to the author to update it.

Hi. Where I can buy this theme?

¿Es posible actualizar este foro para que sea compatible con las versiones 2.1.3 y 4?
