RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Consider background-color, background-size and background-position

The artwork itself looks too small when the installer runs in a resolutions higher than 1024x768 pixels. By considering also the background-size and background-position it should be possible to expand the artwork and cover the visible area in a more more compelling way.
Comment 2 Tru Huynh 2021-06-21 09:19:30 UTC 
possible target for the CentOS Stream Feature Request SIG ?
Comment 3 Carl George 🤠 2021-06-22 19:49:14 UTC 
Ideally this should be done in a way that works for both RHEL and CentOS.  I'm almost done getting all the CentOS modifications into upstream anaconda, I'm not interested in adding more CentOS-only stuff.  I'll defer to the anaconda devs on the best way to approach this.
Comment 4 Vendula Poncova 2021-06-23 13:43:20 UTC 
Hi, the centos-logos package should provide a custom stylesheet with overrides for CentOS. Then Anaconda can set the custom_stylesheet option of the CentOS configuration file to this new stylesheet. This solution can be applied to RHEL 8, RHEL 9 and upstream. We have recently done that for RHEL (see the bug 1928711).
Comment 5 Carl George 🤠 2021-06-24 03:26:43 UTC 
Alain, it sounds like what we need is a custom stylesheet in https://github.com/CentOS/centos-logos/tree/c8/anaconda, then we can put it into the next build of centos-logos.
Comment 6 Alain Reguera Delgado 2021-06-25 02:41:32 UTC 
Yes. I just saw we are already using that model for CS9 (centos-logos:/anaconda/theme/readhat.css). So, let's try it for CS8 as well.

In CS8's case: once we put the css file under centos-logos:/anaconda/theme/, what would happen with the anaconda-gtk.css file in anaconda package? Do we need to touch anaconda and centos-logos spec files, so they don't try to copy the same file?

I've validated the usage of `background-size` and `background-position` to scale the image on different resolutions. They work the way expected. I did the test rebuilding the iso with the changes inside, then run  virtual machine passing the `vga=ask` parameter in anaconda boot screen an selecting different resolutions available there. Reference used https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html-single/customizing_anaconda/index#customizing-graphical-elements_branding-and-chroming-the-graphical-user-interface

By using `background-size: contain;` the results obtained were better than using `background-size: cover;`. The artwork scales proportionally on different resolutions covering the entire area. The sidebar-bg.png expands horizontally while topbar-bg.png expands vertically. The relation between the background-image and the background-color is still very important to achieve a nice fading effect. Here I attach some screenshots of the tests.

This image illustrates the issue. Note the empty space on the right side of the background image. The fading effect was removed from the background image to make the space wasted more visible. This empty space is even wider on larger screen resolutions when image is not scaled.

The image doesn't scale to the container height, so part of the image is lost. Compare with previous screenshots.
Comment 18 Carl George 🤠 2021-06-26 02:30:49 UTC 
These changes are available upstream in version 85.6 [0], which has been built as centos-logos-85.6-1.el8 [1].  I'll run a compose for this next week sometime.

Comment 19 Carl George 🤠 2021-07-02 22:28:31 UTC 
We discovered that this custom stylesheet will also need a small patch for anaconda.  I've submitted that to the upstream rhel-8 branch [0], referencing this bug.  I've already applied it as a "debranding" modification to the CentOS anaconda-33.16.5.2-1.el8 build [1].  A test compose confirmed this works now, so I'll push those builds out soon.
