How to modify the lms webpage?

Hello everyone,
Does anyone know how to customize the LMS webpage. Like if I want to introduce some css styling and want to change some content and add the instructors photo beside the course then how can I do that??

Please help me if somebody knows how to do this…
Thank you

Hello there… You will have to edit /apps/erpnext/erpnext/www/lms/macros/card.html or hero.html

Put css code in 

 {% block head_include %}
{% endblock %}

You can also put links to custom css.
