Hi Netlify Team, I am building apps using react and I noticed some odd behavior after deploying. (across all my Netlify apps) Sizing and margins are changing and do not look at all like on my local. I also run a local build (npm run build) to verify that there are no issues with my code. I didn’t find any and my local build looks as it should. Now I am wondering if Netlify is adding any styles when deploying builds using react? ![Screen Shot 2020-10-02 at 13.02.33](https://global.discourse-cdn.com/netlify/original/3X/b/5/b5c082f457d13cc4cf6ea29dd9004a14d9570d6b.png) Please help me as this issue makes it impossible to work. Thanks Julia ---

I have the issue across all my Netlify projects. The latest one is: ecstatic-brahmagupta-5eab95 thanks for your help! ---

Hi Perry, No, I don’t think its a case issue. As I mentioned I have the issue across all pages in all the projects I deploy with Netlify. Feel free to check also here: romantic-stonebraker-2ab3db It is not that there are files missing or anthing like that. As you can see in the image I attached. Everything is larger. Margins and sizing are not accurate. I was running a local build on my machine and it looked fine. It’s not a new issue I see only now. I have the issue since I use Netlify. It just came to a point where I really need to get rid of this issue. Thanks, Julia ---

hey julia, i’m seeing some interesting things. when i pull up that second url, i see the same error in the console: ![image](https://global.discourse-cdn.com/netlify/original/3X/4/7/479ebaefa3370f455513ee747a47093b4a2a35c2.png) a little googling brings me here: > which seems to indicate that the issue is relating to a an extension. (if you are also seeing the same error, then it is likely an extension we both have installed.) if i view the same site in an incognito window (so, without extensions) i see this: ![image](https://global.discourse-cdn.com/netlify/original/3X/1/2/1238dd59c867333a86edf742a59348f1aac2dea6.png) no JS error. Can you check your sites in an incognito window and tell me whether they are loading correctly? if yes - then it is not a netlify issue, if no, then it is something unrelated to these browser issues and may require a bit more detective work. ---

Hey Perry, I sadly do not have the error you are experiencing. Not in both examples. I attach images. Incognito is also showing the same margin and sizing issue. As in the image posted initially. The sizing seems to change after deploying to Netlify. There is a huge difference in the same browser and the same window size on the same monitor between my local and the Netlify build. ![Screen Shot 2020-10-05 at 21.43.42](https://global.discourse-cdn.com/netlify/original/3X/8/b/8bcfd2f4d04b5161e8a187460524d34fce938146.png) ---

hi there, can you show us a screenshot of what it is supposed to look like vs. what it actually looks like? thanks. ---

It should be like it is displayed on my local and when deploying locally. I am attaching the image again. You can see in the image that the sizing is totally different in the Netlify version. Thank you, Julia ![Screen Shot 2020-10-02 at 13.02.33](https://global.discourse-cdn.com/netlify/original/3X/b/5/b5c082f457d13cc4cf6ea29dd9004a14d9570d6b.png) ---

Hi Perry, I found the issue a minute ago. It was after all on my side. 😓 I am super, super sorry for making you break your head on my issue. Thank you so much!! 🙂 Julia ---

Hi Yasser, The issue was in the end not with Netlify after all. It was a browser issue. Crome was set to a zoom that only happened on my local. If you experience your issue also only on one browser and or only on your local. Check the zoom. 🙂 ---

Thanks for sharing. That is exactly what I need (although I might add a bit more: since I am using an old monitor, the style is wrong in my code; for all future reader)
