+Hanken Grotesk Variable Font
+============================
+
+This download contains Hanken Grotesk as both variable fonts and static fonts.
+
+Hanken Grotesk is a variable font with this axis:
+  wght
+
+This means all the styles are contained in these files:
+  HankenGrotesk-VariableFont_wght.ttf
+
+If your app fully supports variable fonts, you can now pick intermediate styles
+that aren’t available as static fonts. Not all apps support variable fonts, and
+in those cases you can use the static font files for Hanken Grotesk:
+  static/HankenGrotesk-Medium.ttf
+  static/HankenGrotesk-Bold.ttf
+  static/HankenGrotesk-ExtraBold.ttf
+
+Get started
+-----------
+
+1. Install the font files you want to use
+
+2. Use your app's font picker to view the font family and all the
+available styles

+
+## Overview
+
+### The challenge
+
+Users should be able to:
+
+- View the bar chart and hover over the individual bars to see the correct amounts for each day
+- See the current day’s bar highlighted in a different colour to the other bars

+# Frontend Mentor - Expenses chart component
+
+![Design preview for the Expenses chart component coding challenge](./design/desktop-preview.jpg)
+
+## Welcome! 👋
+
+Thanks for checking out this front-end coding challenge.
+
+[Frontend Mentor](https://www.frontendmentor.io) challenges help you improve your coding skills by building realistic projects.
+
+**To do this challenge, you need a decent understanding of HTML, CSS and JavaScript.**
+
+## The challenge
+
+Your challenge is to build out this bar chart component and get it looking as close to the design as possible.
+
+You can use any tools you like to help you complete the challenge. So if you've got something you'd like to practice, feel free to give it a go.
+
+We provide the data for the chart in a local `data.json` file. So you can use that to dynamically add the bars if you choose.
+
+Your users should be able to:
+
+- View the bar chart and hover over the individual bars to see the correct amounts for each day
+- See the current day's bar highlighted in a different colour to the other bars
+- View the optimal layout for the content depending on their device's screen size
+- See hover states for all interactive elements on the page
+- **Bonus**: See dynamically generated bars based on the data provided in the local JSON file
+
+Want some support on the challenge? [Join our community](https://www.frontendmentor.io/community) and ask questions in the **#help** channel.
+
+## Where to find everything
+
+Your task is to build out the project to the designs inside the `/design` folder. You will find both a mobile and a desktop version of the design. 
+
+The designs are in JPG static format. Using JPGs will mean that you'll need to use your best judgment for styles such as `font-size`, `padding` and `margin`. 
+
+If you would like the design files (we provide Sketch & Figma versions) to inspect the design in more detail, you can [subscribe as a PRO member](https://www.frontendmentor.io/pro).
+
+You will find all the required assets in the `/images` folder. The assets are already optimized.
+
+There is also a `style-guide.md` file containing the information you'll need, such as color palette and fonts.
+
+## Building your project
+
+Feel free to use any workflow that you feel comfortable with. Below is a suggested process, but do not feel like you need to follow these steps:
+
+1. Initialize your project as a public repository on [GitHub](https://github.com/). Creating a repo will make it easier to share your code with the community if you need help. If you're not sure how to do this, [have a read-through of this Try Git resource](https://try.github.io/).
+2. Configure your repository to publish your code to a web address. This will also be useful if you need some help during a challenge as you can share the URL for your project with your repo URL. There are a number of ways to do this, and we provide some recommendations below.
+3. Look through the designs to start planning out how you'll tackle the project. This step is crucial to help you think ahead for CSS classes to create reusable styles.
+4. Before adding any styles, structure your content with HTML. Writing your HTML first can help focus your attention on creating well-structured content.
+5. Write out the base styles for your project, including general content styles, such as `font-family` and `font-size`.
+6. Start adding styles to the top of the page and work down. Only move on to the next section once you're happy you've completed the area you're working on.
+
+## Deploying your project
+
+As mentioned above, there are many ways to host your project for free. Our recommended hosts are:
+
+- [GitHub Pages](https://pages.github.com/)
+- [Vercel](https://vercel.com/)
+- [Netlify](https://www.netlify.com/)
+
+You can host your site using one of these solutions or any of our other trusted providers. [Read more about our recommended and trusted hosts](https://medium.com/frontend-mentor/frontend-mentor-trusted-hosting-providers-bf000dfebe).
+
+## Create a custom `README.md`
+
+We strongly recommend overwriting this `README.md` with a custom one. We've provided a template inside the [`README-template.md`](./README-template.md) file in this starter code.
+
+The template provides a guide for what to add. A custom `README` will help you explain your project and reflect on your learnings. Please feel free to edit our template as much as you like.
+
+Once you've added your information to the template, delete this file and rename the `README-template.md` file to `README.md`. That will make it show up as your repository's README file.
+
+## Submitting your solution
+
+Submit your solution on the platform for the rest of the community to see. Follow our ["Complete guide to submitting solutions"](https://medium.com/frontend-mentor/a-complete-guide-to-submitting-solutions-on-frontend-mentor-ac6384162248) for tips on how to do this.
+
+Remember, if you're looking for feedback on your solution, be sure to ask questions when submitting it. The more specific and detailed you are with your questions, the higher the chance you'll get valuable feedback from the community.
+
+## Sharing your solution
+
+There are multiple places you can share your solution:
+
+1. Share your solution page in the **#finished-projects** channel of the [community](https://www.frontendmentor.io/community). 
+2. Tweet [@frontendmentor](https://twitter.com/frontendmentor) and mention **@frontendmentor**, including the repo and live URLs in the tweet. We'd love to take a look at what you've built and help share it around.
+3. Share your solution on other social channels like LinkedIn.
+4. Blog about your experience building your project. Writing about your workflow, technical choices, and talking through your code is a brilliant way to reinforce what you've learned. Great platforms to write on are [dev.to](https://dev.to/), [Hashnode](https://hashnode.com/), and [CodeNewbie](https://community.codenewbie.org/).
+
+We provide templates to help you share your solution once you've submitted it on the platform. Please do edit them and include specific questions when you're looking for feedback. 
+
+The more specific you are with your questions the more likely it is that another member of the community will give you feedback.
+
+## Got feedback for us?
+
+We love receiving feedback! We're always looking to improve our challenges and our platform. So if you have anything you'd like to mention, please email hi[at]frontendmentor[dot]io.
+
+This challenge is completely free. Please share it with anyone who will find it useful for practice.
+
+**Have fun building!** 🚀

+* new exersice after long time
+now will be learning https://github.com/a-h/templ
+it's a templating solution for go, more similar to jsx
+but it also needs a pre-processing step, so i'm adding it like tailwind
+
+with Makefile for make run/live
+and will need to add as a step in project build
+
+* setting up 
+https://git.sunshine.industries/efim/golang-templ-and-tailwind
+have separate repo, but i guess i'll remove .git from this dir,
+to have single commits across Learning HTMX?
+
+or maybe magit will just allow for simple integration?
+just not pushing into origin, committing, and then committing from overall repository?
+
+** not so simple, but still quite OK!
+
+there's now 'subtree' which is separate concept from submodule,
+and it is maybe simpler:
+
+https://magit.vc/manual/magit/Subtree.html
+
+i'm using the repo url
+ssh://gitea@git.sunshine.industries:65433/efim/golang-templ-and-tailwind.git
+
+and the command magit subtree add,
+specify the directory, and it gets embedded it seems.
+i have one level magit dispatch and my notes would be committed to the main repo,
+i would potentially be able to pull in commits from the parent?
+
+and maybe somehow contribute, but yeah, this is still confusing 🙂
+how would i commit to subtree upstream if there are conflicting changes?
+maybe i'll just get denied, as simple as that.
+
+allright! let's add exercise specific data (again)
+
+* so, starting dev
+
+old process:
+1. open second browser and open png with style
+   first mobile
+2. enable view C-S-m in firefox
+   the responsive mode
+
+i suppose next is adding colors to tailwind configuration?
+from the styleguide file
+
+also
+3. check desktop style, whether any big rearrangements are required
+   so that i'd start mobile with way to rearrange things
+
+do i have a separate note with all of these things?
+i've also used some commands to vertically center my stuff
+
+** DONE allright, tailwind config go
+font, size, colors
+
+** well, i don't really want to go on.
+but yeah, i'll need hierarchy of the elements.
+
+** ok. thoughs:
+the componets would be
+- my balance bubble
+  because it is spacially separate
+- spending summary
+- graph inside spending summary
+  or maybe don't even need that
+
+the component should take up all space provided to it.
+if parent would want to add space around - that's easy to do,
+but if component insists on adding space around itself - harder to reuse?
+because then if parent would want to have child take up all space - negative padding?
+
+*** allright, @ to include sub templates
+
+** well, last part? preparing the docker container for deployment on Render.com?
+
+which port should be used?
+also, this would be first time i'll add templ as a build step
+
+** for some reason image doesn't work well
+
+podman run -d -p 9090:8080 localhost/expenses-chart:latest  /nix/store/l4r6glmzbvkhg97lp4dn7nm76w6hz41g-expenses-chart-0.0.1/bin/temp-exercise

+
+oh, well
+
+** you know what - i give up
+
+for some reason when i open url to app running in container,
+and it's on the 8080 port of the host machine - the static files are served
+
+if i use any other port of local machine, to forward into container,
+the static files are not served
+
+maybe this is bug in go? i don't know
+StripPrefix doesn't seem to do anything
+
+and for some reason in this specific exercise CMD doesn't work in the container
+so let's just give up!
+
+i could try to write a docker file and check with that, but yeah
