Using CSS, you can set the display of two buttons and a search bar in the following way:

css
 
 
Copy code
.container {
  display: flex;
  justify-content: space-between;
}

.button {
  flex: 1;   
}

.search {
  display: flex;
  flex-basis: 41rem;
}

You can stick a footer to the end of an HTML page by setting the position property to fixed on the footer in your CSS.

css
 
 
Copy code
footer {
  position: fixed;
  bottom: 0;
}

Horizontal scroll is a tool that you can use to scroll horizontally across a webpage or screen. It can be achieved by setting the CSS overflow property to "scroll" on the element you would like to scroll horizontally.

Example:

css
 
 
Copy code
div {
    overflow-x: scroll;
}

You can change the color of <hr> by setting a custom background-color property in the CSS. For example, the following code will set the <hr> color to red:

css
 
 
Copy code
hr {
    background-color: red;
}

You can use the CSS width and height properties to control the size of an image:

css
 
 
Copy code
img {
  width: 400px;
  height: 300px;
}

That is likely because you are only defining a single dot element in your HTML and are assigning a color class to that single element. To target multiple elements, you will likely need to use a CSS selector. For example, if you wanted to change the color of all paragraphs in a div with a class of 'example', you could use the following CSS code:

css
 
 
Copy code
.example p {
    color: #f00;
}

css
 
 
Copy code
span {
  display: inline-block;
}

To use a tag with inline-block, you can add the display: inline-block CSS style to the tag, like this example:

You can use

css
 
 
Copy code
position: absolute;
bottom: 0;

to position a button at the bottom of a div. In the <style> section of a HTML document, you can use the code above to apply this styling to the desired button.

To position a button on the bottom of a div, you can use CSS with the position, left, right, bottom properties.

For example:

css
 
 
Copy code
div {
  position: relative;
}

button {
  position: absolute;
  left: 0;
  right: 0;
  bottom: 0;
}

To move images on a landing page, use CSS position and top, bottom, right, and left properties to set the position of the element.

For example, in HTML:

html
 
 
Copy code
<img src="example.jpg" alt="example image" class="example-img">

In CSS:

css
 
 
Copy code
.example-img {
 position: absolute;
 top: 20px;
 left: 350px;
}

This will set the image's position 20 pixels from the top and 350 pixels from the left.

CSS stands for "Cascading Style Sheets" and it's a style language that web developers use to make websites look more appealing to the user. It's similar to how you might style your clothes - you choose what colors and shapes you like to put together to create a specific look. CSS tells the web browser which colors, fonts, shapes, sizes, and backgrounds to use on a website.

CSS stands for Cascading Style Sheets. It is a stylesheet language used for describing the look and formatting of a document written in HTML (or other markup language). CSS is used to control the presentation of web pages and user interfaces written in HTML and XML, including the layout, colors, and fonts.

CSS can be written within a HTML document using <style> tags. It can also be written in an external stylesheet which can then be imported into the HTML by using a <link> tag.

More info and examples about writing CSS can be found at MDN Web Docs

You can limit horizontal scrolling in media query by setting overflow-x: hidden; within your media query.

For example:

css
 
 
Copy code
@media only screen and (max-width: 600px) {
  body {
    overflow-x: hidden;
  }
}

First, set the flex container to have display: flex. Then, you can use the justify-content property to set the alignment of the flex items along the horizontal axis. To disable justify-content: center when using media queries, you should use the following code:

css
 
 
Copy code
@media (max-width: 600px) {
  .container {
    display: flex;
    justify-content: flex-start; /* Disable justify-content: center */
  }
}

Using the flex box model, you can center an image within a container by setting the container's display style to flex, the justify-content style to center and the align-items style to center:

css
 
 
Copy code
.container {
  display: flex;
  justify-content: center;
  align-items: center;
}

The best way to make a text paraghragh tidy in HTML is to use CSS. You can add the style attribute and define the desired style (e.g. font, size, color), or you can add classes/IDs to the paraghragh and define their styling in an external stylesheet. For example:

css
 
 
Copy code
.paragraph {
    font-family: Arial;
    font-size: 16px;
    text-align: center; 
    color: grey;

}

Then use it in your HTML like so:

html
 
 
Copy code
<p class="paragraph"> Lorem ipsum dolor sit amet. </p>

You will likely need to add a :hover selector to the css for the element with the button. For example if your button has a class of btn, then you will want to add CSS like so:

css
 
 
Copy code
.btn:hover {
  background-color: #CCCCCC;
}

With display: flex, you can divide the website in 3 vertical columns with the same size using a combination of flex-direction: row and flex: 1 on the child elements.

css
 
 
Copy code
.container {
  display: flex;
  flex-direction: row;
}

.column {
  flex: 1;
}

CSS can be connected to HTML by using the <link> tag. This must appear in the <head> element of the HTML document. The href attribute should be set to the path of the CSS file. An example is below:

code
 
 
Copy code
<head>
  <link rel="stylesheet" type="text/css" href="stylesheet.css">
</head>

The correct way to send an image behind a text with z-index is by setting the z-index of the background image to a higher value than the z-index of the text. An example of this in HTML and CSS code is given below.

css
 
 
Copy code
.background-img {
  position: absolute;
  z-index: -1;
}

.text {
  position: relative;
  z-index: 1;
}

To center an <h2> vertically in the page, you can wrap the <h2> element in an outer <div> and apply the following CSS:

css
 
 
Copy code
div { 
  display: flex; 
  align-items: center;
}

You can put images side by side by using the HTML <div> element. For example, the following HTML code puts two images side by side:

html
 
 
Copy code
<div>
  <img src="image1.jpg" />
  <img src="image2.jpg" />
</div>

You can also use the CSS float property with the left or right value to float elements to the right or left of each other.

For example, to float two images side by side, you could use the following HTML and CSS code:

html
 
 
Copy code
<div>
  <img src="image1.jpg" style="float:left;" />
  <img src="image2.jpg" style="float:left;" />
</div>
