Is rem good for responsive design
Within CSS, em and rem are both scalable units that also specify values of properties. em and rem meet web accessibility standards, and, unlike px , scale better. Consequently, they are more suited for responsive design.
Which unit is best for responsive design
Percentage(%) unit
Percentage is one of the most useful units for creating a responsive or fluid layout. Popular frameworks like Bootstrap, foundation, and Bulma use percentage for their base layout. Here the full-width class will be of 100% width of its parent element.
Is rem or px responsive
Use px for small, fixed-size elements like borders or shadows. Use em for typography and other scalable elements that need to change size relative to their parent element. Use rem for scalable typography and responsive layouts that need to change size relative to the root element.
What is the rem unit for responsive design
In CSS rem stands for “root em”, a unit of measurement that represents the font size of the root element. This means that 1rem equals the font size of the html element, which for most browsers has a default value of 16px. Using rem can help ensure consistency of font size and spacing throughout your UI.
Is REM responsive to screen size
Using rem in all units of your CSS allows you to increase the size of your page (either by layout change or screen size) by simply increasing or decreasing the font-size in the html element.
Is rem better for accessibility
Unlike PX, relative units like %, EM, and REM are better suited to responsive design and also help meet accessibility standards. Relative units scale better on different devices because they can scale up and down according to another element's size.
Should I use PX for responsive design
Absolute Units
But on the device itself, the PX unit is fixed and does not change based on any other element. Using PX can be problematic for responsive sites, but they are useful for maintaining consistent sizing for some elements. If you have elements that should not be resized, then using PX is a good choice.

Why rem is better than pixel
Rem and pixel (px) are two units of measurement frequently used in CSS and HTML to define font size, margin or image size for example. However, the two units have a big difference in terms of web accessibility, because a pixel is not responsive and that's why it'sbetter to use REM.
Is rem responsive to screen size
Using rem in all units of your CSS allows you to increase the size of your page (either by layout change or screen size) by simply increasing or decreasing the font-size in the html element.
Why using rem is better than px
For styling a webpage, we use relative units like em and rem instead of absolute measurements like px (pixels). This is because nowadays, screen sizes come in different sizes and shapes. If we use px , the element's size remains constant regardless of the size of the screen.
Should I use rem or em size
Basically that both rem and em are scalable and relative units of size, but with em, the unit is relative to the font size of its parent element, while the rem unit is only relative to the root font size of the HTML document. The “r” in rem stands for “root”.
Should I always use rem
The relative unit, on the other hand, grows with the default settings of the browser. So this is really an accessibility concern. Therefore, any time you're defining font-sizes, you should absolutely (or relatively) use rems.
What image format is best for responsive design
Use JPGs for photos and PNGs for graphics or other images that require transparency. Use smaller PNG-8 instead of PNG-24 for graphics with a limited number of colors. To decrease the size even further, you can also reduce the number of colors, from 256 to 16. Use SVGs (vector graphic images) for icons and logos.
Which image format is best for responsive website
Use PNGs on your website and social media because they create a sharper, more defined image on digital and mobile displays. Optimize your PNG files for the web by making your file size as low as possible while maintaining good quality.
Should you use rem or em
Use em units for sizing that should scale depending on the font size of an element other than the root. Use rem units for sizing that doesn't need em units, and that should scale depending on browser font size settings. Use rem units unless you're sure you need em units, including on font sizes.
Is it better to use rem
Why should you use rem units As mentioned before, rem units reference the size of the root element. Since a user can set the default size of this element from their browser settings, the webpage can scale to match a user's preference. Using absolute units like pixels, however, creates accessibility barriers.
Why rem is better than em
In CSS, the rem unit is only relative to the document's root element, while the em unit is only relative to the immediate parent of the targeted element. This means that em sizes are inherited from parent elements, while rem sizes are inherited only from the root element.
Should you use rem for spacing
Try to always use rem for font-size. And utilize the benefit of em for the proportionate padding if you need to.
What is the best image size for responsive websites
Most commonly sized 1080 x 1080px, square images are great for in-text images, sidebar ads, and Instagram. 16:9 Panoramic. This is your common website Hero image ratio for standard widescreen sizes. It's often sized 1920 x 1080px and is used in presentations, widescreen TVs, and landscape images.
What image format is best for fast website
Webp is the best format for web.
If high loading speeds are important for you, choose WebP as the image format for your website. JPG and PNG are also good choices for the web. If your choice is between JPG or PNG, use JPG for photos and PNG for logos.
What image format is faster for website
Image format
WebP is usually the most efficient of all web image formats. File size is typically 25-50% smaller than JPEG while keeping the same quality. It supports transparency and alpha too, so is a great alternative to PNG for faster image loading.
Why REM is better than em
In CSS, the rem unit is only relative to the document's root element, while the em unit is only relative to the immediate parent of the targeted element. This means that em sizes are inherited from parent elements, while rem sizes are inherited only from the root element.
Why designers should use REM
If you're designing a site with a flexible width, using rem units for layout measurements can be a good idea. This ensures that the layout will scale with the font size, making it more consistent across different screen sizes.
Should I use rem for images
Use REMs for sizes and spacing. Use EMs for media queries. In summary, both pixels and REMs for media queries fail in various browsers when using browser zoom, and EMs are the best option we have. It's a better practice to use rem instead of pixels if you want a responsive website.
