Dragmath equation editor inserts number of blank lines before it appears
What renderer are you using? Tex filter or MathJax?
MathJax has two output formats - inlineMath and displayMath. Everything inside displayMath-delimiters goes to a new line and everything inside inlineMath-delimiters goes inline (to the same line). So if you are using MathJax check the delimiters...
If you are using tex filter each tex image has a class "texrender" and from core themes only standard theme and splash theme have the necessary css for displaying mathematical notations inline centered. If your theme does not have this css, you can add it to one of your custom theme css files
Many thanks for coming to help. I am using tex filter. Where will I find custom css file to which to add the above code. Kindly let me know.
In your moodle folder /theme/"nameofyourtheme"/style/
Editor.css is used only for editor content area, usually moodle 2 themes have there files like core.css ... and you may need to purge all caches from Site administration > Development > Purge all caches to make moodle use new css.
I am using Standard theme of Moodle and I have checked the core.css. It does contain the .texrender line. Do I have to insert the above lines in other css files under style folder for standard theme? Nevertheless, I purged all cache. However, still I get a lot number of blank rows before any equation. Sorry bothering.
Then it's caused by something else - no need to add that css.
What preview window is it? Quiz/some question type/some activity?
Do you have any custom plugins ( 3rd party blocks etc ) installed? Sometimes different 3rd party activities use the same css classes for different things...
I have installed moodle on Fedora 17. I do not know if the problem of equation display right at the bottom relates to some other file not directly connected with moodle.
On CentOS 6 the same thing is working well.
Is there any other easier way to install some other equation editor if not dragmath? I will be grateful for response.
