Unfortunately, without access to a Mac, I am unable to confirm the accuracy of my suggestions. Providing a screenshot or link to the page might offer more clarity. As there is limited information available, I will attempt to assist in troubleshooting the issue.
My assumption is that the discrepancy lies within the browsers themselves rather than with Bootstrap or any misunderstood differences.
Could you please elaborate on what you mean by "is exactly the same size"? Have both browsers been maximized? Have you manually adjusted their sizes to align perfectly at the edges? It's important to note that browser interface elements such as chrome and scrollbars can vary in size, affecting the viewport dimensions despite appearances indicating otherwise.
The use of .container
with a margin set to auto
allows the browser to calculate margins for fixed-width elements like .container
. The .container
class within Bootstrap offers specified widths for different viewport sizes. It's possible that viewing the page near a breakpoint could result in slight discrepancies due to varying scrollbar sizes or other factors unique to each browser.
For instance:
Bootstrap sets a breakpoint at 992px.
- If Firefox displays your page at 995px viewport width, the
.container
would render at 970px.
- In Safari, if the viewport width measures 990px, the
.container
would be rendered at 750px.
To determine if this issue stems from a breakpoint difference, compare the exact viewport widths of both browsers and adjust them accordingly. If the problem persists, it may not be related to breakpoints specifically.
Any additional details provided would aid in further diagnosis.
I hope this guidance points you towards a resolution.
