How to apply HTML tags inside a bootstrap alert box?

Hi!

It seems very basic, but I couldn't find a solution.

1. I have a controller that will call a blade: return redirect()->route('app.vendor.search', [$variables])->with('info-success', 'File uploaded successfully.');
2. the blade has the following code:

                <div class="alert alert-success alert-dismissible">
                    <button type="button" class="close" data-dismiss="alert" aria-hidden="true">&times;</button>
                    <h4>
                        <i class="icon fa fa-check"></i> Success!</h4>
                        {{ Session::get('info-success') }}
                </div>

1. It works very well.
2. However, if I try something like return redirect()->route('app.vendor.search', [$variables])->with('info-success', 'File <strong>uploaded</strong> successfully.'); the "strong" tag will be ignored. As matter of fact all the tags I've tried were ignored.

Any ideas?

Thanks !!
