Hello,

I saw the screenshots you attached.

1) Please try adding the following Custom CSS in the Custom CSS for Desktop area under Theme Settings >> Custom CSS.

.woodmart-navigation .item-level-0>a {
    padding-right: 17px;
    padding-left: 16px;
}

2) I have visited your website and the text is already in one line.

3) The buttons are also looking fine on my end. It seems that you have managed to fix it.

4) Please try adding the following Custom CSS in the Custom CSS for Desktop area under Theme Settings >> Custom CSS.

li.description_tab.active a {
    visibility: hidden;
}

And check if this works for you otherwise it requires customizations.
