CSS Looks Different in PM Visualizer Browser vs App

Hello, does anybody know why my css looks different in postman visualizer in the browser vs. the desktop app? In the app, my css margins are working and make space between two elements. In the browser, they’re all scrunched up. I’m also using an external library to make a word cloud and I don’t know why it looks different in the app and the browser.

I think the problem with margins happens in my card div container, I gave it a margin of 225 20 30 20 and it seems to be giving that margin on the desktop app but not on browser.

Here’s the link to my collection too if that’s helpful.

Thanks for the link!

Try removing the fixed height on your carousel at the top.

Since you have it set to a fixed height of 30vh, the height of your carousel gets squished when the visualizer window is shorter (you can see the height is different in your web vs desktop screenshot - page zoom also comes into play)

Thank you, this fixed the cards going over my carousel! However, my CSS margins still don’t seem to be recognized in the browser. I want a little space between my carousel and cards, so I added margin to my card container. It works in the app but not browser.

Also, my charts still look really weird in the browser, any idea why that’s happening? I didn’t make the css of the charts so idk what’s going on there

Thanks so much for your help

Sounds a little tricky!

You can right click on the visualizer window and Inspect the visualization using browser dev tools. Click the elements in question may reveal where the strange CSS is being applied in web vs desktop

Thank you, I wasn’t aware I could inspect my visualizations and this helped me solve my margin problem :slight_smile: Appreciate it! The charts are proving to be quite tricky to debug though…

I’m getting this error three times, and I’m assuming it relates to my charts because I have three of them:

‘The Content-Security-Policy directive name ‘frame-ancestors:’ contains one or more invalid characters. Only ASCII alphanumeric characters or dashes ‘-’ are allowed in directive names.’

Any idea on what to fix with this (or even where to start looking - I really have no idea)?

Postman for web has some Content Security Policies set in place to protect from malicious use in the browser setting.

These are not settings you can change on the client side, so you can remove this code from your template

<head>
    <meta http-equiv="Content-Security-Policy" content="frame-ancestors 'all'">
</head>

Is anything broken in your visualization? If you are trying to figure out exactly which elements are introducing the CSP violations, you can try commenting each component out one by one

Yes, all my visualizations are broken and are much smaller than usual. They’re not scaling correctly like they do in the desktop app. I’m guessing the third party library uses iframe to scale the visualization and the browser is blocking it?

I have a feeling the errors are coming from the inline <script> tags in your html template. You are using three separate script tags and calling the same window object (anychart), reassigning the onDocumentReady callback. TI’m not familiar with how anychart works under the hood, but this might be causing it to get confused

Maybe refactoring to have one <script> handle the definition of the callback for anychart.onDocumentReady() would help

See this for example of using multiple anychart charts on the same page:
