Form box inline alignment

Site URL: https://karektr.com/social-media-advertising

Hi I would like to know how to place the e-mail and website block on the same line and run the check boxes 3 on either side instead of the 6 vertically aligned?

Add to Home > Design > Custom CSS

/* Align form block */
@media screen and (min-width:768px) {
div#block-yui_3_17_2_1_1611066368713_353573 .field-list>*:nth-child(n+3) {
    width: 48%;
    float: left;
}
div#block-yui_3_17_2_1_1611066368713_353573 .field-list>*:nth-child(n+5) {
    clear: left;
    width: 100%;
}
}

Hi thank you for your response. I tried it but it doesn't seem to work. I had it working but, somehow delted a piece of code and I'm now getting "missing opening }" in custom css that I cant seem to find.

Can you by any chance help? 

Hi I managed to fix the problem, once again thank you for your response.
