Well I don't know in other countries but where I live, Mexico, it could be work for that. Basically in Mexico there are a lot of companies who don't know anything about web but start getting really small web projects only requiring some html and CSS and using a lot of plugins.
The bad part about it is that, those jobs are low wage and also required other knowledge. I have a friend that does HTML and CSS, basically knows the very basic about it but what she really does is 3D & 2D animation, design, etc. Other very required job are designers with knowledge on web (HTML & CSS).
Those jobs are very low wage, around $455USD every month minus taxes and so.
