Hello,  
How can I widen cells in Jupyter notebook? I tried the fix from [this](https://discourse.julialang.org/t/widen-display-in-ijulia-jupyter-notebook/12470) post, but it doesn’t change anything about my notebook.

```julia
using IJulia
display("text/html", "<style>.container { width:100% !important; }</style>")

```

I also tried this from ChatGPT

```julia
using Markdown
Markdown.html("<style>.container { width:100% !important; }</style>")

```

Any idea why this has no effect on my notebook and other ways to widen the cells? Thanks.

Works for me (you have to make the window wider first, since `width:100%` is relative to the window width).

What’s the window width here? The width of my browser window where I’m running the notebook? It’s full screen. Is there something I have to do in Jupyter settings?

See the following example, in which the input cell starts narrower than the browser window and then expands to match the window width:

Thanks for this! It’s been much needed.

Note that (a) it was [posted 6 years ago](https://discourse.julialang.org/t/widen-display-in-ijulia-jupyter-notebook/12470/4) (and a similar solution [7 years ago](https://discourse.julialang.org/t/decrease-margins-of-ijulia-in-jupyter-notebook/6912/2)) and (b) the `using IJulia` is not needed.

I’ve tried this, and as you can see my window doesn’t expand. Am I entering something wrong?

Looks like it [changed in Jupyter version 7](https://stackoverflow.com/a/76778615/3662120). The new command is:

```julia
display("text/html", "<style>:root { --jp-notebook-max-width: 100% !important; }</style>")

```
