How to make my header font bold?

Hi,

I added this code in the additional CSS area to make my headlines Raleway and bold. It worked to make it Raleway but its not bold. Can you please let me know where is my mistake?

Many thanks !

/Edit Header/ .section-header h3 {

font-size: 35px;
font-weight: bold;
font-family: raleway;
color: black;
}

Hello there,

I hope you are doing well today.

This font cannot get any bolder it seems.If you set the font-bold property to 100 it will reduce the boldness but it cannot go much further.

I am sorry for the inconvenience caused here.

Best Regards,
