Styling Demo 13
There are some issues on styling on Demo 13 such as rounded corners.
Please note that that is the design as this demo uses no rounded corners.
You are welcome.
However if you like to use this demo with rounded corners you just need to remove the below code from
// Border radius
$enable-rounded: false !default;
$border-radius: 0 !default;
$border-radius-sm: 0 !default;
$border-radius-lg: 0 !default;
Then recompile your assets folder with Gulp or Webpack.
Please note that the build tools are required only in the development environment just to compile the assets when the source folder files are modified. In the hosting/server deployment you will only need the compile assets, no need to install the build tools dependencies there.
