How to use/re-sue custom complex css (like webkit-keyframes mover) in blazor?

Question

User-2009437049 posted

I am trying to implement css styles in sample application.

I'm using blazor in an application, but found some problem with UI designing.

I created a simple Employee form with bootstrap. Now i want to create some styles and then re-use it. This is the actual css which needs to be implemented.

.register {
background: -webkit-linear-gradient(left, #3931af, #00c6ff);
margin-top: 3%;
padding: 3%;
}

.register-left {
text-align: center;
color: #fff;
margin-top: 4%;
}

.register-left input {
border: none;
border-radius: 1.5rem;
padding: 2%;
width: 60%;
background: #f8f9fa;
font-weight: bold;
color: #383d41;
margin-top: 30%;
margin-bottom: 3%;
cursor: pointer;
}

.register-right {
background: #f8f9fa;
border-top-left-radius: 10% 50%;
border-bottom-left-radius: 10% 50%;
}

.register-left img {
margin-top: 15%;
margin-bottom: 5%;
width: 25%;
-webkit-animation: mover 2s infinite alternate;
animation: mover 1s infinite alternate;
}

@-webkit-keyframes mover {
0% {
transform: translateY(0);
}

100% {
transform: translateY(-20px);
}
}

@keyframes mover {
0% {
transform: translateY(0);
}

100% {
transform: translateY(-20px);
}
}

.register-left p {
font-weight: lighter;
padding: 12%;
margin-top: -9%;
}

.register .register-form {
padding: 10%;
margin-top: 10%;
}

.btnRegister {
float: right;
margin-top: 10%;
border: none;
border-radius: 1.5rem;
padding: 2%;
background: #0062cc;
color: #fff;
font-weight: 600;
width: 50%;
cursor: pointer;
}

.register .nav-tabs {
margin-top: 3%;
border: none;
background: #0062cc;
border-radius: 1.5rem;
width: 28%;
float: right;
}

.register .nav-tabs .nav-link {
padding: 2%;
height: 34px;
font-weight: 600;
color: #fff;
border-top-right-radius: 1.5rem;
border-bottom-right-radius: 1.5rem;
}

.register .nav-tabs .nav-link:hover {
border: none;
}

.register .nav-tabs .nav-link.active {
width: 100px;
color: #0062cc;
border: 2px solid #0062cc;
border-top-left-radius: 1.5rem;
border-bottom-left-radius: 1.5rem;
}

.register-heading {
text-align: center;
margin-top: 8%;
margin-bottom: -15%;
color: #495057;
}

line reports a problem and I have no idea with it since I'm a newbie with blazor. What should I do in my code?

Application built with asp. Net core 3.0", "blazor preview 9".

Output: I tried to follow guides and looked up example implementations but could not solve the issue.

I am getting the following exception:

Severity Code Description Project File Line Suppression State
Error The attribute names could not be inferred from bind attribute 'bind-value'. Bind attributes should be of the form 'bind' or 'bind-value' along with their corresponding optional parameters like 'bind-value:event', 'bind:format' etc. EMS.Client C:\S\S\Client\Pages\AddEm.razor 6

asked.

I want to use css styles in blazor razor page. I think I have no option except keeping the css styles in variables and then using it with html elements. Can anyone suggest me? How ll I use key-frames or other complex css styles? – maifs just now.

Hi fdfdfdf,

You could try to use @attribute to add css style on the div like:

<div  @attributes="register" class="container">
    <div class="row">
        <div class="col-md-4 @register-left">
            Test data
        </div>
    </div>
</div>

@code {
    public Dictionary<string, object> register  =
        new Dictionary<string, object>()
        {        
            {"style", "background: -webkit-linear-gradient(left, #3931af, #00c6ff);margin-top:3%;padding:3%" }
        };
}
