Fix home page responsiveness

[AnnaGabriela]

Since one of the most important features of the product is to be accessible from any device, the responsiveness should be fixed. Currently, the whole responsiveness is misconfigured (see images below). Let's work with at least these min-width breakpoints: 576px, 768px, 992px. What do you guys think? @jvpessoa10 @antonioalmeidab

Changing this issue to enhancement, since 16dae38 fixes this behavior. But I think we can make the project more mobile friendly in the future, since this would require creating a considerable amount of mobile specific code.

I say we start developing the components with responsiveness in mind, just so we won't have too much rework later (specially since later is like next week heheh).
