Plasma/KDE clock widget you can layout and style using HTML/CSS!
Similar look of the above images is just because I quickly crafted them using the same markup and colors foundation (plus I use it that way myself :). So worry not, you are not limited to neither these layouts, nor colors, nor information types shown, as you can use QT's subset of HTML and CSS to make yours layout look as you like. Please explore the configuration dialog!

HTML Clock widget is very flexible and configurable by design. Almost all important aspects of its behavior can be modified or overriden.
This pane allows you to select one of predefined layouts or tell the widget you want to use your own (defined in "User Layout" pane).
- Layout: selects widget built-in clock layout.
- Use user layout: uses user layout, instead of built-in one.
- Transparent background: by default, widget uses theme provided background color. When this option is checked, widget background is no longer drawn, making it fully transparent. Note: this option is hidden on Plasma 5.19 as it introduces similar feature for the all widgets which is preferred. option to built-in or newer these version.
- Use custom font: enables use of custom font (and its size) instead of theme default.
- Select font: opends font dialog to select new typeface to use. You can also specify font size.
- Locale to use: By default, the system wide locale settings are used while creating day labels.
If you want to override this (i.e. have English originated day labels while your whole system uses different language,
enable this option and put name of locale of your choice (i.e.
ploren_GB). Ensure such locale is available in your system. - Timezone offset: by default, widget shows your local time. But if you want to use different time zone than your
local, enable this option and provide the offset in form of
[+-]HH:MM, i.e.-03:30or5:00. If no sign is specified, positive (+) offset is assumed. Faulty offset falls back to00:00(which meansGMTtime zone). - Container fill width: By default clock container takes as much horizontal space as needed to render its content. This may be incorrect behavior if i.e. you use vertical panel and would like to use custom background color. In such case you'd end up having ugly side borders if your clock contant is taking less space than panel's width. To combat this, enable this option to force the widget. NOTE: this option is most useful if you use this widget in a dock/panel. For desktop widgets it's recommended to keep it off.
- Container fill height: By default clock container takes as much space as needed to render its content. This may be incorrect behavior if i.e. you use horizontal panel and would like to use custom background color. In such case you'd end up having ugly borders on the top and bottom if your clock contant is taking less vertical space than panel's occupies. To combat this, enable this option to force the widget to take as much vertical space as its parent container allows. NOTE: this option is most useful if you use this widget in a dock/panel. For desktop widgets it's recommended to keep it off.
Aside from using built-in layouts, you can (and probably will) create your own, either completely from scratch or using one of built-in layouts as your base.
- Clone: Copies the selected built-in layout's markup and parameters to text edit area editor.
- Select font: is part of "font helper" feature. Select any font from installed on your machine and you will see its
family name shown. Note that name is shown using selected font, so it may not really be readable in case of fonts
like dingbats.
- Copy Click the "Copy" button to have font family copied to the clipboard (then you can use in text area with regular CTRL-V keyboard paste shortcut).
- Copy as HTML: Clicking this button will put complete HTML snippet using
<span>styled to use font you selected to the clipboard, i.e.<span style="font-family: Noto Sans; font-size: 16px; font-weight: bold;">Text</span>.
- Select color: similar to "font helper", it's color helper. Select any color to see its
#RRGGBBvalue.- Copy: Puts your color to the clipboard using
#RRGGBBnotation. - Copy as HTML: Puts
<span>styled to use your color to the clipboard, i.e.<span style="color: #9d7837;">Text</span> - Copy as CSS: Puts CSS
color: #RRGGBB;to the clipboard.
- Copy: Puts your color to the clipboard using
- Style selection: This section allows you to apply font, color (or both) to currently selected part of layout.
- Retain selection: By default selection is clered once style is applied. When this option is checked, selection will be retained and updated to cover replaced text.
Even if set your font size directly in markup, custom font's size still matters and influences the whole layout, affecting i.e. default spacing between elements. If you are trying to make your layout compact, it's recommended to select custom font size to
1and set the text size using i.e. CSS.
Configures built-in calendar view, shown (by default) when you tap on the widget.
- Enabled calendar view: uncheck to disable calendar view popup from showing up on widget click.
- Show week numbers: specifies if popup calendar view should also show week numbers.
Configures widget tooltip information, shown when you hoover over the widget.
- Main text: template for main tooltip text line.
- Sub text: template for tooltip subtext line.
Both HTML layout or tooltip string can contain anything you like, however certain sequences are considered placeholders, and will be replaced by corresponding values, all other elements are returned unaltered.
These are date and time related, and will return values based on your current calendar/clock and system timezone settings.

For example, Today is {DDD} will produce Today is Sunday (assuming today is named "Sunday").
You can also use optional formatting directives. The syntax is {PLACEHOLDER:DIRECTIVE}
and supported directives are:
| Directive | Description |
|---|---|
| U | Turns whole placeholder uppercased (i.e. "{DD:U}" => "SAT") |
| L | Turns whole placeholder lowercased (i.e. "{DD:L}" => "sat") |
| u | Turns first letter of placeholder uppercased, leaving remaining part unaltered. This is useful when i.e. weekday or month names are usually lowercased in your language but you'd like to have it other way. I.e. for Polish localization, "{DDD}" can produce "wtorek" for Tuesday. With "{DDD:u}" you would get "Wtorek" instead. |
| 00 | Ensures placeholder value is at last two characters (not just digits!) long by adding leading zeros to shorter strings. Longer strings will not be trimmed. Also note zeroes will be prepended unconditionally, even if that would make no much sense, i.e. {D:00} produce 0M on Mondays. |
These are extra placeholders that are implemented to work around limitation of QT's supported HTML/CSS.
| Placeholder | Description |
|---|---|
| {flip:XX:YY} | Will be replaced by value given as XX for every even second and with value specified as YY for every odd second. This can be used to do some animation or other tricks. Both XX and YY can be almost any text you want and can be used in any place of your layout, so you can flip parts of your CSS style, HTML markup or even flip other placeholders, as {flip} is always processed separately as first one. |
:as part of flipped value is currently not supported and will cause odd effects if tried. This unfortunately got further implications and affects the following functionality:
{flip}can't be nested into other{flip},- while you can use other placeholders as
{flip}arguments, they must not use formatting modifiers,- you cannot flip HTML markup with embedded CSS due to
:being CSS separator. You can flip part of CSS separately though.
- QT support for HTML and CSS is not covering all features available, so here are some tricks you can pull to achieve effects offten desired while creating new clock.
- Want custom background color for your widget? Just ensure your template uses
<body>tag and set itsbgcoloras you like. Remember that you also need to enable eitherContainer fill widthorContainer fill heightdepending on your desired orientation. - To get 100% in vertical orientation, set
<BODY>'swidthattribute to100%(i.e.<body width="100%">) or use CSS - To get 100% in vertical height, try set
<BODY>'sheightattribute to100%(i.e.<body height="100%">) You may also want to set
Blinking seconds (usually shown in a form of blinking : separator placed between hours and minutes.
Unfortunately we cannot use CSS animators here as these are not supported by QT implementation. But we can do some
smart tricks with text colors, as fortunately for us, QT supports CSS colors as well as its alpha channel (aka
transparency). So to make thing blink, we will be simply cycling between fully transparent and fully opaque
every second. To achieve that effect, you need to use special placeholder called {flip:XX:YY}, which is simply
replaced by XX on every even second, and by YY on every odd second.
Knowing that CSS color format is #AARRGGBB where AA is alpha channel value from 00 being fully transparent
to FF (255 in decimal) being fully opaque, we can do this:
<span style="color: #{flip:00:FF}ffffff;">BLINK!</span>
But if you want, you can also blink by toggling whole colors:
<span style="color: {flip:#ff0000:#00ff00};">BLINK!</span>
<span style="color: {flip:red:green};">BLINK!</span>or by using QT supported SVG color names:
<span style="color: {flip:red:green};">BLINK!</span>You can use {flip} as many times as you want, so you can easily achieve this:
<span style="color: {flip:#ff0000:green};">{flip:THIS:BLINKS}!</span>
As already mentioned, you can also flip other placeholders:
{flip:{MMM} {dd}, {yyyy}:Today is {DDD}}
You should be able to install HTML Clock widget either using built-in Plasma Add-on installer
or manually, by downloading *.plasmoid file either from project
Github repository or
from KDE Store
To install widget using Plasma built-in mechanism, press right mouse button over your desktop or panel and select "Add Widgets..." from the context menu, then "Get new widgets..." eventually choosing "Download New Plasma Widgets...". Then search for "HTML Clock" in "Plasma Add-On Installer" window.
Download *.plasmoid file from project Release section.
Then you can either install it via Plasmashell's GUI, by clicking right mouse button over your desktop or panel and
selecting "Add widgets...", then "Get new widgets..." eventually choosing "Install from local file..." and pointing to downloaded
*.plasmoid file.
Alternatively you can install it using your terminal, with help of kpackagetool5:
kpackagetool5 --install /PATH/TO/DOWNLOADED/htmlclock.plasmoid If you already have widget running and there's newer release your want to install, use kpackagetool5
with --upgrade option. This will update current installation while keeping your settings intact:
kpackagetool5 --upgrade /PATH/TO/DOWNLOADED/htmlclock.plasmoidNOTE: Sometimes, due to Plasma internals, newly installed version may not be instantly seen working, so you may want to convince Plasma by doing manual reload (this will NOT log you out nor affect other apps):
