Google font locally with different weights but with the same name

Question

Here's my problem:

In order to improve my SPEED mark on google speed insight, I had to switch from render-blocking google fonts to loaded locally google fonts.

So far so good except that I have a HUGE problem.

Before I was loading my fonts in this way:

<link href="https://fonts.googleapis.com/css?family=Open+Sans:300,400,600,700|Open+Sans+Condensed:300|Ubuntu+Condensed|Ubuntu:300,700" rel="stylesheet">

And in my huge style-sheet, I was just calling them normally for example:

body {
  font-family: 'Open Sans', sans-serif;
  font-weight: 400;
}

But now, since I had to download them to avoid the render-blocking red flag, I'm calling them in this way:

@font-face {
    font-family: "Opens Sans";
    src: url("/fonts/OpenSans-Regular.ttf");
    font-style: normal;
    font-weight: 400;
}
@font-face {
    font-family: "Opens Sans";
    src: url("/fonts/OpenSans-Light.ttf");
    font-weight: 300;
}
@font-face {
    font-family: "Opens Sans";
    src: url("/fonts/OpenSans-Bold.ttf");
    font-weight: 600;
}
@font-face {
    font-family: "Opens Sans";
    src: url("/fonts/OpenSans-ExtraBold.ttf");
    font-weight: 700;
}
@font-face {
    font-family: "Opens Sans Condensed";
    src: url("/fonts/OpenSansCondensed-Light.ttf");
    font-weight: 300;
}
@font-face {
    font-family: "Ubuntu Condensed";
    src: url("/fonts/UbuntuCondensed-Regular.ttf");
    font-weight: 300;
}
@font-face {
    font-family: "Ubuntu";
    src: url("/fonts/Ubuntu-Regular.ttf");
    font-weight: 300;
}
@font-face {
    font-family: "Ubuntu";
    src: url("/fonts/Ubuntu-Bold.ttf");
    font-weight: 700;
}

And here you can see my PROBLEM.

I call different fonts with the same name, but they have different weights. Obviously, I can call them with a different name, for example, "Ubuntu Bold" but then I would have to change my entire stylesheet, for example, I should now declare:

body {
      font-family: 'Open Sans Normal', sans-serif;
      // font-weight: 400; //
}
p {
      font-family: 'Open Sans Bold', sans-serif;
      // font-weight: 700; //
}

Essentially, no more font-weight, only different font-family names to state the weight.

Is there any solution to my problem?

Even though the font files are different, you don't need to set a different font-family for each variation of the font. You can just set one font-family, and specify the different variations in the different @font-face properties.

You should define each @font-face with the same font-family name, like so:

@font-face {
    font-family: 'Opens Sans';
    src: url("/fonts/OpenSans-Regular.ttf");
    font-style: normal;
    font-weight: 400;
}
@font-face {
    font-family: 'Opens Sans';
    src: url("/fonts/OpenSans-Italic.ttf");
    font-style: italic;
    font-weight: 400;
}
@font-face {
    font-family: 'Opens Sans';
    src: url("/fonts/OpenSans-Bold.ttf");
    font-style: normal;
    font-weight: 600;
}

Note that each different font file has a separate @font-face with different properties that correspond to the specific font file, but they have the same font-family. You can then use the font in your css like so:

body {
    font-family: 'Open Sans', sans-serif;
    font-weight: 400;
}
.bold {
    font-family: 'Open Sans', sans-serif;
    font-weight: 600;
}
.italic {
    font-family: 'Open Sans', sans-serif;
    font-style: italic;
}

The other properties in your css classes (font-weight, font-style, etc) will determine which @font-face is used.
