1. 1) Let’s start with HTML markup. We will separate the first letter with <span> tags so we can animate it independently…

<div class="button">
    <p><span>H</span>ome</p>
</div>

… and give it basic CSS

.button {
    margin: 30px;
    width: 160px;
    height: 60px;
    border: 1px solid black;
}

2) Align the text inside

.button p {
    line-height: 60px;
    text-align: center;
    font-size: 25px;
    font-weight: 900;
}

3) Now we do a little hack. We want to animate the first letter without affecting the alignment of the rest of the word. We have already separated the first letter with <span> element. Let’s make the letter itself invisible and give the <span> element position property, so we can attach another absolutely positioned element to it:

.button span {
    color: transparent;
    position: relative;
}

Display the actual letter inside with a help of ::before pseudo element

.button span::before {
    content: 'H';
    position: absolute;
    width: auto;
    height: 60px;
    color: black;
}

This way our text stays aligned correctly and we are free to animate the first letter however we want without causing layout re-flow.

4) Next we want to create black block the same size of our button, which will appear and slowly rotate on hover. Give the button relative position

.button {
    ...
    position: relative;
}

… and create a block using ::after pseudo element. At first it’s hidden with 0 opacity – background-color: rgba(0,0,0,0);

.button::after {
    content: '';
    position: absolute;
    top: 0; 
    left: 0;
    width: 100%;
    height: 100%;
    background-color: rgba(0,0,0,0);
    transition: .8s;
    z-index: 1;
}

5) To create our hover effect we need to do few things. First we need to push the text in front of the black block. Z-index only works on elements with position property:

.button p {
    ...
    position: relative;
    transition: .8s;
    z-index: 10;
}

We will also be animating <span>::before element that holds the first letter. Let’s give it transition property:

.button span::before {
    ...
    transition: .2s ease-out;
}

We want the black box to rotate slowly on hover, become visible and our text in <p> and <span> elements to turn white:

.button:hover::after {
    background-color: rgba(0,0,0,1);
    transform: rotate(10deg);
}
.button:hover p {
    color: white;
}
.button:hover span::before {
    color: white;
}

6) Finally we animate the first letter. You can experiment with this, I decided to make it rotate 360 degrees

.button:hover span::before {
    color: white;
    transform: translate(-65%, -10%) rotate(360deg);
    font-size: 80px;
}

Final HTML:

<div class="container">
    <div class="button">
        <p><span>H</span>ome</p>
    </div>
    <div class="button">
        <p><span>P</span>roducts</p>
    </div>
    <div class="button">
        <p><span>A</span>bout</p>
    </div>
    <div class="button">
        <p><span>C</span>ontact</p>
    </div>
</div>

Final CSS:

body {
    background-color: white;
}
* { margin: 0; padding: 0; box-sizing: border-box; }

.button {
    margin: 30px;
    width: 160px;
    height: 60px;
    border: 1px solid black;
    position: relative;
}
.button p {
    position: relative;
    transition: .8s;
    line-height: 60px;
    text-align: center;
    font-size: 25px;
    font-weight: 900;
    z-index: 10;
}
.button span {
    color: transparent;
    position: relative;
    
}
.button span::before {
    content: 'H';
    position: absolute;
    width: auto;
    height: 60px;
    color: black;
    transition: .2s ease-out;
}
.button:nth-of-type(2) span::before {
    content: 'P';
}
.button:nth-of-type(3) span::before {
    content: 'A';
}
.button:nth-of-type(4) span::before {
    content: 'C';
}
.button::after {
    content: '';
    position: absolute;
    top: 0; 
    left: 0;
    width: 100%;
    height: 100%;
    background-color: rgba(0,0,0,0);
    transition: .8s;
    z-index: 1;
}
.button:hover::after {
    background-color: rgba(0,0,0,1);
    transform: rotate(10deg);
}
.button:hover p {
    color: white;
}
.button:hover span::before {
    color: white;
    transform: translate(-65%, -10%) rotate(360deg);
    font-size: 80px;
