Once I first began Pop!_OS on my model new laptop (truly my first Desktop Laptop) about one yr and a half in the past, a fast take a look at its minimalistic interface made me respect its design from the very begin. It was one of many cleanest Linux distros I had tried, however having used a MacBook air for the previous 3 years there was one thing lacking in comparison with macOS’s design.

During the last yr, Pop!_OS saved bettering its design, one of the important adjustments has absolutely been the cosmic dock. That is how Pop!_OS seems to be by default (with macOS icons) on my second display screen:

With this sort of design, even the Apple group is getting fearful. However there’s extra: you don’t like one thing? you’ll be able to all the time change it!

Please word that this text is supposed for GNOME customers (and partly for all customers utilizing GTK), in case you are utilizing KDE you’ll discover different sources to realize the identical outcomes. If you happen to use Home windows or macOS, I counsel you create a Pop!_OS digital machine in your laptop to do this out (possibly you’ll find yourself utilizing it as the first working system).

There’s a purpose why the above picture is of my secondary display screen: it solely shows the dock. There isn’t a prime bar, no app-switcher popup (cmd+tab), no workplaces-switcher dialog, no app-search enter, and so forth. All these are issues (together with the look of your home windows) which you can modify to your liking as CSS code. That is attainable since Gnome (and never solely gnome) helps customized themes.

On this brief article, I’ll present you get your palms on the CSS code you’ll have to alter your working system’s look, and a few recommendations on navigate that code, as a result of it received’t be that simple.

In case you have been utilizing Linux for some time, you would possibly a someplace seen a .themes folder in your house listing, in the event you haven’t, then now it’s about time you do.

What we’ll do is principally clone the OS’s default theme (or the theme you might be presently utilizing), and modify its CSS code to our liking.

Let’s begin by cloning the default theme in your themes listing:

cd ~/.themes
git clone https://github.com/heytdep/Custom-Pop-_OS-Dark.git

I additionally suggest putting in GNOME tweaks so as to change themes away from the command line: sudo apt set up gnome-tweaks .

You’ll primarily be working solely with two information of your newly created Customized-Pop-_OS-Darkish theme: Customized-Pop-_OS-Darkish/gnome-shell/gnome-shell.css and Customized-Pop-_OS-Darkish/gtk-3.0/gtk.css . The primary will mean you can modify the general look of your os: prime bar, workspace switcher, app switcher, search field, prime bar menus, calendar, software search, and so forth. Then again, the gtk CSS file can modify the looks of your apps: motion bar, reduce maximize and shut buttons, and so forth.

I’ve personally not tweaked a lot the unique design since I already preferred it a lot, however I did change a number of issues:

  • prime bar
  • topbar menus
  • app corners
  • app switcher

High Bar

Head over to the gnome-shell.css file and seek for the /* High Bar */ remark. The CSS code inside #panel will inform GNOME what your prime bar ought to appear to be. What I did right here is: change the background and textual content coloration, and alter the peak (made it smaller). I’ve additionally added a hover property to the bar’s buttons so they’re highlighted on hovering them:

#panel .panel-button:hover 
background-color: rgba(43, 43, 43, 0.281);
box-shadow: none;

High Bar Menus

Having modified the colour of the highest bar, I’ve additionally modified the colours of the highest bar menu popups, once more a easy background-color: and coloration: will do the trick. You can see the proper selectors as you learn beneath the highest bar CSS code.

App Switcher

Equally to the highest bar, looking for /* App Switcher */ ingnome-shell.css will observe down the selector for the Functions switcher. From there you’ll have the ability to modify its properties when an app is chosen or outlined within the switcher:

.switcher-list .item-box:outlined     background-color: rgba(246, 246, 246, 0.3);   
.switcher-list .item-box:chosen background-color: rgba(246, 246, 246, 0.3); coloration: #F6F6F6;

If you wish to additionally change the switcher’s design moreover its app containers, you’ll must seek for the .switcher-list class, which is chosen in line 31 together with different parts. If you happen to want to solely replace the switcher with out impacting the opposite parts, merely take away .switcher-list from .workspace-switcher-container, .switcher-list, .resize-popup, .osd-window (line 31), and choose it alone:

.switcher-list   coloration: #F6F6F6;  background-color: rgba(44, 44, 44, 0.7);  border-radius: 12px;  padding: 12px; 

Altering the Apps’ Corners

I like my Apps’ corners to be extra rounded than within the default settings, in the event you do too open the Customized-Pop-_OS-Darkish/gtk-3.0/gtk.css file, discover the next code fragment:

.background .titlebar:backdrop, .background .titlebar   border-top-left-radius: 4px;  border-top-right-radius: 4px; 

And alter the roundness as you want by modifying the 2 border-radius properties.
