Hi Professor [~aloraine],

Is inline CSS necessary on all the pages ? The changes really look ugly, there are classes which are already present in the code, just restoring the css in base.css (Deleted as a part of old css but was required) would do the work. The changes look good to me, but the code looks ugly.

Thank you for asking. I defer to your judgement in this matter. If in some situations the in-line css makes code harder for others to understand and maintain, or is horribly repetitive, then please do not use it. Use your judgement as you are representing the developer point of view.

My apologies for muddying the water of the discussion and for making more work for you. Since Sameer Shanbhag is more experienced with django and css than I am, I defer to his opinion here.

Sai Supreeth Segu : Could you look for changes done to base.css and check which classes were deleted which were required by the Submit app page. I can help you with that if you want.

Restored the Submit App page as in AppStore 1.0.

I'm sorry, I got confused.

The latest master branch on https://devappstore5.bioviz.org "submit app" page seems to be already fixed. Was this maybe done in a prior commit?

Please ignore the previous comment! I was wrong about that.

I have a request for Sai Supreeth Segu:

I'm nervous about adding a lot of style classes to "base.css" that are only ever going to be needed on this one page.
Can we please remove all the submit-app specific style from "base.css" and instead place those classes into a single .css file named after the django app that actually uses them. In this case, it would be called "submit_app.css".
Piling loads and loads of stuff into "base.css" makes it super hard to maintain and improve appstore. I feel that the "base.css" file is already too big and complicated. Also, putting submit_app specific stuff into base.css means that other developers working on other pages or django apps will be tempted to use those same classes. If they do that, then it will be much harder to make a change to the submit_app page.

Makes Sense. @Supreet Could you create a new submit_app folder under static which will have a css folder and inside that css folder there will be aubmit_app.css

Dr. [~aloraine] and Sameer Shanbhag, I have made changes and created a new upload_form.css in /static/submit_app/css folder.
