Theme development

I have installed a couple of new themes and I have just found out I cannot edit colors for example using CorporateClean all but one of the color styles has a padlock at the side. if I change the color is states that the file cannot be saved. All modules that have color editing state the same. Looking through the posts it all I can find that the color folder in sites is read-only but all the folders in root are read-only. Colors is selected in Modules.

I am working on a local copy of the site on my PC using XAMPP. I have administrator rights

I'm a designer and I don't know git.
A friend of mine has placed my theme on drupal.org (using my login)
It's now a sandbox project: https://www.drupal.org/sandbox/drupaltronic/2365217
I have made a clone on my computer using git-tower.
I want to push a new branch revisions to drupal.org but what format of repository URL do I have to use?

Hi Drupal community,

I am new to drupal and have some problems with website theme development in it.
I have learned regarding the template file and Theme Dev module, I can search for name and override some functions.
But I can't change values of $node. I feel that I lost in the drupal 7 docs.
Can you please describe be rough flowchart how I should do to get my custom html node rendering? And changes values for vars in $node and render it after it. I am need just a small general flowchart for theme development.

Thanks,
Sergey

I want to add href to all img tags on my drupal post. My bellow code is working fine on html page but on drupal doesn't work(do not do anything):
Code:

I have 5 links that use the same background image.

I am trying to place different text onto each background image. This text will act as a hyperlink.

I’ve achieved this task in dreamweaver but i’m wondering if this is something that views and panels or some other module can achieve without the coding.
I’ve tried adding text to the image using photoshop, but the text is not sharp.

Does anybody know how I should approach this?
Is this something that I will have to hard code?

This seems to be a simple task. I seem to be having a mental block.

Hi guys,

I'm implementing a responsive Google Maps iframe on my drupal website and stumbled upon a problem: the iframe doesn't adapt to max-height: 500px; in my stylesheet.
