There is a calculator that is well displayed in modern browsers. But in ie8 it does not work correctly! For some reason they disappeared: before and: after the brackets of .brackets. The display of absolutely positioned letters in the tables has flown, and in general it does not want to use width: 100%; text-align:center width: 100%; text-align:center . Apparently position relative does not want to be applied. How can this be fixed?
.matrix_b { tbody{ &:before{ content: 'B'; position: absolute; font-size: 20px; bottom: -50px; width: 100%; text-align: center; } } }
