Hi I have a few questions about Intel XDK I'm trying to create apps with the design section and the coding and I find that when I try to insert a color onto fonts for instance on the header with coding in the css folder. I click save all and when I run the simulator it works, as soon as I go back into the design section of the platform the color font reverts back to default which is white. How can I keep the color from reverting back to default?
Short Answer: make your own CSS file and make the change you want there.
Long Answer: that CSS file is auto-generated. If you look at the top of it, there is a warning there informing you of that fact and warning you that any changes you make there will be lost when the CSS is next updated. It is generated from a .less file. My advice is to just leave that .less file and that main .css file alone and add in your own.
Then I find that when I'm in the coding side and go back to the design section the loading phase takes way too long.
Hmm - that is way too long. I've never seen it take that long. Is your design particularly large? How many pages and sub-pages are in it? How many widgets?
