I am trying create a hover effect using CSS. Here is the link: http://creativeartbd.com/demo/test.html
Here is the code:
/* GENERAL BUTTON STYLING */
button,
button::after {
-webkit-transition: all 0.3s;
-moz-transition: all 0.3s;
-o-transition: all 0.3s;
transition: all 0.3s;
}
button {
background: none;
border: 3px solid red;
border-radius: 5px;
color: red;
display: block;
font-size: 1.6em;
font-weight: bold;
margin: 1em auto;
padding: 2em 6em;
position: relative;
text-transform: uppercase;
}
button::before,
button::after {
background:red;
content: '';
position: absolute;
z-index: -1;
}
button:hover {
color: black;
}
/* BUTTON 5 */
.btn-5 {
overflow: hidden;
}
.btn-5::after {
/*background-color: #f00;*/
height: 100%;
left: -35%;
top: 0;
transform: skew(50deg);
transition-duration: 0.6s;
transform-origin: top left;
width: 0;
}
.btn-5:hover:after {
height: 100%;
width: 135%;
}
<button class="btn-5">Button 5</button>
now if you run it you can see that there is style when you hover over the button. Now I want to set initial background for this button. So that IF I set the background here:
button {
background: orange;
}
If I do so then the effect is not showing.
Can you tell me why and how can I solve it?

Answer 1

add z-index:0 to the element to create a stacking context and keep the pseudo element inside. You can then add background
/* GENERAL BUTTON STYLING */
button,
button::after {
-webkit-transition: all 0.3s;
-moz-transition: all 0.3s;
-o-transition: all 0.3s;
transition: all 0.3s;
}
button {
background: none;
border: 3px solid red;
border-radius: 5px;
color: red;
display: block;
font-size: 1.6em;
font-weight: bold;
margin: 1em auto;
padding: 2em 6em;
position: relative;
z-index:0;
background:orange;
text-transform: uppercase;
}
button::before,
button::after {
background:red;
content: '';
position: absolute;
z-index: -1;
}
button:hover {
color: black;
}
/* BUTTON 5 */
.btn-5 {
overflow: hidden;
}
.btn-5::after {
/*background-color: #f00;*/
height: 100%;
left: -35%;
top: 0;
transform: skew(50deg);
transition-duration: 0.6s;
transform-origin: top left;
width: 0;
}
.btn-5:hover:after {
height: 100%;
width: 135%;
}
<button class="btn-5">Button 5</button>
You can also simplify your code like follow:
button {
background: none;
border: 3px solid red;
border-radius: 5px;
color: red;
display: block;
font-size: 1.6em;
font-weight: bold;
margin: 1em auto;
padding: 2em 6em;
background:
linear-gradient(50deg,red 50%,transparent 50.5%),
orange;
background-size:250% 100%;
background-position: right;
text-transform: uppercase;
transition: all 0.5s;
}
button:hover {
color: black;
background-position: left;
}
<button class="btn-5">Button 5</button>
