My custom CSS Hacks

After many years of experience with UI and web design i have collected a small but nice list of my favoite CSS hacks that I use on pretty much every project, app or website.

I hope you can learn from this and use it in turn for your projects too.

Add your favorite CSS hacks in the comments below!

1. Custom Grid

.grid {
    position: relative;
    margin: auto;
    width: 1200px;
}
@media(max-width: 1200px) {
.grid {
width: 95%;
}
}

This allows you to set a custom grid to work inside and you can edit this grid for different device screen widths.

1. Design a custom close icon

.close {
    position: absolute;
    padding: 5px;
    font-style: normal;
    font-weight: 600;
    transform: scale(1.4);
    cursor: pointer;
    width: 20px;
    height: 20px;
    transition: all 0.3s;
    z-index: 900;
}
.close::before {
    position: absolute;
    top: 4px;
    left: 12px;
    transform: rotate(-43deg);
    content: '|';
}
.close::after {
    position: absolute;
    top: 4px;
    left: 14px;
    content: '|';
    transform: rotate(43deg);
}

I design a custom icon element and wherever i need to use it in my html i simply add this line:

<i class="close"></i>

1. CSS Vars

Some CSS can be long and hard to remmeber so i just store it inside a CSS variable and that's it.

:root {
--gradient: linear-gradient(324deg, rgba(119,0,255,1) 0%, rgba(41,4,255,1) 100%);
}

I can then simply call it in my css like this:

.box { background: var(--gradient) }

1. Make everything border-box

* {
box-sizing: border-box
}

this way all my elements will be uniform in dimensions and i don't have to worry about padding and borders and whatnot messing up with my widths and heights.

1. Get a quick spacer element Sometimes i need to add a quick spacer between elements

.spacer { height: 60px }

And i call it in my html:

<div class="spacer"></div>

1. Custom Scrollbars

::-webkit-scrollbar {
    width: 10px;
    height: 10px;
} 
::-webkit-scrollbar-track {
    background: #eee; 
    border-radius: 50px;
}
::-webkit-scrollbar-thumb {
    background: green;
    border-radius: 50px;
}

That one customizes scrollbars, pretty cool.

1. Custom Highlighter

::selection {
    background: red;
    color: white;
}

1. Remove dependency on !important To remove dependencies on !important for cnflicting styles i simply make every selector very specific like:

.app .container .box h1 { color: green; }

Instead of setting styles like

.app h1 {color:green;}

Then if i need a more abstract style definition
i use:

.app h1 { color:green }
.app .container .box h1.title {color:red}

Hope you enjoyed these!
