Slight CSS Alignment issues in Chrome

Question

While I am new to stack oveflow, it has always been a great source for answers for me, and I've largely been successful in my work. I've built quite a lot of HTML 5 banner ads using GSAP (Greensock Animation Platform) in my time, but now I am stumped with this ever so slight CSS alignment issue that is driving me nuts and I would like to understand why it is happening on Chrome, but not on Firefox.

I have screenshots to better illustrate the alignment issues:

Answer 1

Ok I found out the issue and resolved it.

The reason for this was because I use Sublime Text to edit my HTML files, and I also use a plugin called HTML-CSS-JS Prettify to "clean" up my code. In this cleaning process it auto formats my code by adding carriage returns to <br/> tags and indenting tags which is great.

Unfortunately this plugin has a flaw with it's indentation instead of doing "tab" a bunch of times to indent my code, it simulates this by creating four "space" characters per "tab". These spaces render only as one on HTML, but none the less messed up my alignment.

If anyone else uses this program and this plugin (which are great btw) I got around this by going into HTML-CSS-JS Prettify plugin's preferences, navigated to "unformatted" I added, "br", "BR" to the end of the list.

This will basically ignore trying to auto format any <br/> or <BR> tags with those silly ( ) hack indentation.

Answer 2

If you consider four spaces instead of tabs as bug/workaround, then why not to think about rendered page without tabs (assume they were not replaced) as malfunction?

Using spaces only is just another way of code formatting and should not be, in my opinion, confused with tabulation or, like you said, "tab simulation". Word 'indentation' is more accurate I think.

However, replacing tab with spaces is not a bug.
