Dobry den,
deje sa to na tejto adrese http://bakchus.webnamieru.sk/ kde by som ja chcel aby ciara oddelujuca jednotlive aktuality bola 1px siroka a zelenej farby tak ako nadpisy clankov.
Moj styl:
div.spaceline hr (riadok 277)
{
color: #427c00;
height: 1px;
}

{
height: 1px;
border-top-width: 1px;
border-right-width-value: 1px;
border-right-width-ltr-source: physical;
border-right-width-rtl-source: physical;
border-bottom-width: 1px;
border-left-width-value: 1px;
border-left-width-ltr-source: physical;
border-left-width-rtl-source: physical;
border-top-style: solid;
border-right-style-value: solid;
border-right-style-ltr-source: physical;
border-right-style-rtl-source: physical;
