With the T3 Framework setup/structure, what approach is best to override/amend Bootstrap's grid.less and variables.less (located in plugins/system/t3/base-bs3/bootstrap/less/) as I need to add additional code at specific lines in both files?
Customization in the t3 plugin is not recommended as when you upgrade, the changes could be lost. Any customization should be implemented in the template: templates/t3_bs3_blank/
The files in template will override the same files in t3 plugin. In case you want to customize the grid.less file and variables.less file, here is the tip:
- The variables.less file is already available in the template folder: templates/t3_bs3_blank/less, open the file and do customization
- The grid.less file is not included in the template folder so please copy the file from t3 plugin to the folder: templates/t3_bs3_blank/less, open the new file and do customization.
